Garden of Spaces is a sort of sonic sculpture, fully notated but permitting various sections of the orchestra to time their entrances differently at each performance. Rautavaara has created thematic material, unlike so many such pieces, that seemingly makes sense given these parameters, and so the music comes across as coherent, shapely, and quite haunting.

But the outstanding work here is the new Clarinet Concerto for Richard Stoltzman. Rautavaara seems to have a special feeling for the instrument. In the score of his opera Aleksis Kivi, the composer restricts the woodwind contingent to two clarinets, used to magical effect, and this concerto certainly ranks among the most successful in the modern repertoire. While full of virtuosity and some incredibly difficult-sounding writing in the clarinet's highest register, the most memorable moments occur where Rautavaara exploits the instrument's unparalleled ability to sing in tones of liquid lyricism. The central slow movement in particular must rank as one of the most purely beautiful in Rautavaara's (or anyone else's) entire output.

It goes almost without saying that as the dedicatee Stoltzman plays with total commitment, and as usual in this series the contributions of Leif Segerstam and the Helsinki Philharmonic are ideal. Excellent sonics, warm and well-balanced (in the concerto) round out another magnificent contribution to the Rautavaara discography.
