The product available here for purchase is the solo flute part and piano reduction for John La Montaine's Concerto for Flute.
Premiered on April 12, 1981 by Keith Bryan and the National Gallery Orchestra, John La Montaine's Concerto for Flute and Orchestra is best summed up in this review from Paul Hume at The Washington Post: "The world premiere of a flute concerto by John La Montaine was the centerpiece. La Montaine clearly had a great time writing the concerto, since he filled it with wit and open, songful beauty. The formal design is neatly broken up into imaginative divisions. There are some exotic touches for woodblocks, and bass clarinet, but the heart of the work lies in the brilliance of the writing for the soloist. The cadenza in the final movement is impressively introduced and beautifully concluded."
