The BIS odyssey of recording the orchestral works of Kalevi Aho, 
            one of the world’s leading composers continues. By my reckoning 
            this release is the twelfth in the BIS series and it features Aho’s 
            latest offering: his Fifteenth Symphony.
             
            The history of classical music is littered with colourful stories 
            of disastrous premieres. In March 2011 I was in the Bridgewater Hall, 
            Manchester for the world premiere of this symphony. Performed by the 
            BBC Philharmonic under Juanjo Mena, any fears that the first performance 
            might join that list of luckless premieres proved unfounded and Aho 
            was called to the stage in response to the enthusiastic audience response.
             
            A joint commission with the BBC Philharmonic and the Lahti Symphony 
            Orchestra the Fifteenth Symphony is a substantial work lasting 
            just over half an hour. Aho has described the score as “the 
            apotheosis of the dance” in deference to the influence 
            of Beethoven's Seventh Symphony. He has given descriptive 
            titles to the symphony’s four movements: Nebbia (Mist/Haze); 
            Musica bizzarra (Bizarre music); Interludio 
            (Interlude) and Musica strana (Strange music). 
            This immediately approachable symphony holds the attention and contains 
            much impressive and fascinating writing. It’s predominantly 
            uplifting in character and just bubbles along with remarkable reserves 
            of energy. My enduring impression is of the highly rhythmic and colourfully 
            exhilarating writing. This is often imbued with an exotic Middle Eastern 
            character and punctuated with liberal use of percussion much of which 
            is for hand-drums. The start of Nebbia suggests a winter 
            scene of walking through fog at night, maybe, in a city in the early 
            hours. Although the fog begins to lift there remains an increasing 
            atmosphere of menace before the music decays away. There is an exotic 
            flavour to the Musica bizzarra with wide dynamics that swiftly 
            shift in mood. The writing is especially percussive complete with 
            prominent use of bongos, congas, darbuka and djembe. Evoking a chilly 
            winter picture the Interludio confers an uneasy calm interrupted 
            by brisk, fierce figures on the strings. Markedly percussive, Musica 
            strana (Strange music) inhabits a fascinating sound-world 
            once again with striking use of wide dynamics. Here Aho’s writing 
            establishes a raucous temperament that exudes vitality.
             
            Composed in 2008, Minea was a commission by the Minnesota 
            Orchestra who premièred it the next year under Osmo Vänskä. 
            This virtuosic score lasting nineteen minutes was written with the 
            intention that each member of the orchestra has something significant 
            to play. Aho writes “formally, Minea is distantly reminiscent 
            of Indian rāgas” however other influences of Oriental music 
            are evident such as Arabian music. The composer seems intent on expanding 
            the traditional world of classical music with writing that clearly 
            focuses on unusual rhythms. Typical of Aho’s compositions is 
            the use of wide dynamics together with marked contrasts of orchestral 
            weight and character. This Impressive, compelling and accessible score 
            deserves to be widely known.
             
            When composing his Concerto for Double Bass and Orchestra 
            in 2005 Aho stated that he was careful not to allow the orchestra 
            to drown out the sound of the solo instrument. He employs lighter 
            textures during the solo passages. To ensure familiarity with the 
            potential of the double bass Aho borrowed an instrument from Eero 
            Munter who commissioned the score. Munter gave the first performance 
            in 2005 at Lahti. Playing continuously the concerto is cast in five 
            movements, two of which are cadenzas. The dark-hued opening 
            Moderato, Passionato is inhabited by mysterious 
            scurrying figures. The “intensely songful ” description 
            given to the movement by Aho doesn’t really work for me. The 
            second movement Cadenza I has the double-bass played exclusively 
            with pizzicato - often of a feather-light quality. A real 
            highlight is movement three which is characterised by its Presto 
            outer sections energetically performed with the freshness of spring. 
            By contrast the Tranquillo section creates an atmosphere 
            of unerring calm. Altering from its conventional register the double-bass 
            is played with harmonics throughout. Also a cadenza for the 
            double bass movement four, entitled Misterioso, includes 
            two percussionists that really dominate the writing with their penetrating 
            sounds. It’s remarkable how Aho successfully creates an unearthly 
            atmosphere where time almost stands still. The Finale marked 
            Andante - Allegro ritmico contains music of an ominous, rather 
            threatening quality. Gradually increasing in weight, an impressive 
            climax ensues before gradually fading into the sound of the soloist 
            tapping and knocking the wood of the double-bass. Owing to the low, 
            dark sound characteristics of the double bass the instrument seldom 
            stands out like a solo instrument in a traditional concerto. It feels 
            more like part of the orchestra. I fear the solo double bass would 
            be almost inaudible in a concert hall. Nevertheless this is a most 
            impressive score and one that I will play again soon.
             
            I have only praise for the Lahti Symphony Orchestra displaying an 
            unfailing instinct for Aho’s turbulent sound-world of absorbing 
            textures and enticing rhythms. Each conductor seems impeccably prepared 
            and maintains a firm grip, securing alert and involving performances. 
            Eero Munter playing a Guadagnini (Turin 1770) and clearly relishes 
            the artistic and technical demands asked of his instrument.
             
            In the BIS booklet Aho has written the essay himself. He provides 
            a real insight into the three works. The disc reviewed is a Hybrid 
            SACD that I played on my standard player. The engineers have provided 
            excellent sound quality that is full and sharply focused. For anyone 
            wanting to hear the fascinating and accessible music of Kalevi Aho 
            for the first time this outstanding release would make an ideal embarkation 
            point.
