This CD is a real showcase for the talents of the young JACK Quartet who specialize 
                  in late twentieth-century and contemporary music. I would have 
                  loved to attend the concert at the Wigmore Hall from which this 
                  recording was taken, but will have the opportunity to hear them 
                  live when they come to the Barns at Wolf Trap near Washington, 
                  DC next January. There, in addition to the Ligeti Quartet No. 
                  2, they will perform the Brahms Clarinet Quintet (with clarinetist 
                  Derek Bermel) -something outside their normal repertoire. Here 
                  they are clearly at home and produce as exciting performances 
                  as one is likely to hear of these works.  
                  
                  Although the booklet notes are rather detailed and an interesting 
                  read, they are really inadequate when it comes to giving background 
                  on either the works or the quartet. The quartet, which first 
                  played together in 2003 as students at the Eastman School of 
                  Music in Rochester, New York, chose their name based on the 
                  first letter of each of their first names. Thus, we know what 
                  the acronym JACK stands for! They now reside in New York City 
                  and perform throughout the world both in concert venues and 
                  alternative locations. They have already made a name for themselves 
                  in their sterling performances of contemporary music. The programme 
                  here, therefore, is typical. 
                    
                  Of the four works presented on this disc one has become a classic, 
                  Ligeti’s Quartet No. 2 was composed for the LaSalle Quartet, 
                  and has received quite a number of superbly recorded performances. 
                  The JACK Quartet studied with the Arditti Quartet, who contributed 
                  the Ligeti quartets in Sony’s Ligeti Edition and have 
                  nothing to fear here from their illustrious predecessor. They 
                  also measure up well to two other current favorites, those by 
                  the Parker Quartet on Naxos - which I reviewed here earlier 
                  and which won a Grammy Award in 2011 - and the Artemis Quartet 
                  on Virgin Classics. Those recordings were part of all-Ligeti 
                  programmes while this performs a different but equally valuable 
                  function by allowing the listener to compare and contrast chamber 
                  works that have some things in common - creating music purely 
                  as sound at times with dynamic extremes and complex technical 
                  challenges - but that are individual and easily identified as 
                  uniquely by their composers. One would never mistake the Ligeti 
                  for a work of someone else, though it also shows the influence 
                  of his Hungarian forebear, Bartók, in its five-movement 
                  structure. The third movement, Come un meccanismo di precisione, 
                  with its pizzicato plunking like some machine gone awry, is 
                  similar to the one he included in the Chamber Concerto he composed 
                  around the same time, and is one of Ligeti’s trademarks. 
                  The JACK Quartet captures the many moods of the quartet well 
                  including its humour, but also the introspection pervasive in 
                  the final movement. 
                    
                  The other quartet that may be familiar to listeners is the Xenakis 
                  Tetras, one of this composer’s best-known chamber music 
                  pieces. This is JACK Quartet’s second recording of it, 
                  as they included it in a studio recording as part of the Mode 
                  label’s “Xenakis Edition”. They sound here 
                  as if they are having a great deal of fun with all the effects 
                  Xenakis provides them, at one point (cue up 2:18) sounding like 
                  a bunch of laughing apes! The work cannot be easy to play, however, 
                  and contains enough variety to keep the listener engaged throughout 
                  its lone 16-minute movement. Tetras (“four” in ancient 
                  Greek) was written for the Arditti Quartet, so again interpreting 
                  it is second nature to the JACKs. 
                    
                  The remaining works on the CD provide a contrast to the more 
                  boisterous Ligeti and Xenakis. It is quite a shock going from 
                  either of these to John Cage’s Quartet in Four Parts 
                  with its quiet, vibrato-less writing sounding like something 
                  out of the Middle Ages, except for the harmony and the odd outburst. 
                  It is based in part on an Indian view of the four seasons with 
                  the movements representing 1) Summer: Quietly Flowing Along; 
                  2) Autumn: Slowly Rocking; 3) Winter: Nearly Stationary; 
                  and 4) Spring: Quodlibet. The quartet may sound simple 
                  at times but its unusual combination of chords and rhythmic 
                  structure provide a complexity that is not readily apparent 
                  without a score. After an austere third movement depicting winter, 
                  the finale comes as a jolt with its tune like some Renaissance 
                  dance that stays in the mind long after the work has ended. 
                  The Quartet in Four Parts is one of the last pre-aleatoric 
                  works Cage composed shortly after his Sonatas and Interludes 
                  for Prepared Piano. It is especially good to have included 
                  this quartet on the programme as the release of the CD coincides 
                  with Cage’s centenary. 
                    
                  The second work on the disc is also the newest, Matthias Pintscher’s 
                  Study IV. John Fallas in the booklet notes the strong 
                  personal relationship between the composer and the JACKs, though 
                  the present work apparently was not composed for them. In many 
                  ways it is the most unusual and the most “advanced” 
                  composition here: the lower strings are “prepared” 
                  by inserting metal paperclips near the bridge of the instruments 
                  and the viola’s C and G strings are “retuned”. 
                  This results in a very weird, veiled sound that I am certain 
                  John Cage would have approved. Except for some sudden plunks, 
                  the work is mostly static and very quiet. Of the four works 
                  on the disc, I found this one the hardest to like and think 
                  if I saw it in performance I would have had a greater appreciation 
                  of it. Nonetheless, the JACK Quartet obviously know their way 
                  around it. 
                    
                  For anyone who heard them live at this Wigmore Hall concert, 
                  this CD is the perfect memento. However, the attraction of the 
                  particular sequence and the stunning performances captured in 
                  lively and natural sound further make this disc highly recommendable 
                  for anyone with an interest in modern chamber music. It whets 
                  the appetite for more from the JACK Quartet.
