As it turned out, it was the Piccolo Concerto by Lowell Liebermann. The work, which was commissioned by the National Flute Association, was written in 1996 and first performed by Jan Gippo. The first recording of the work was put out by James Galway (the recording we heard on the radio that day) in 1998. It is GLORIOUS. The opening of it is simply amazing and beautiful. Seriously. I know a lot of people want to avoid all modern music but don't avoid listening to this work. The first movement alone is worth listening to.
One reviewer said of it "This delightful work was full of eerie beauty and rollicking good humor." I think that sums it up entirely too well.
You can listen to James Galway perform the work on youtube.
I. Andante comodo (Seriously...if you listen to ANYTHING here listen to this movement)
II. Adagio: Part 1 | Part 2 (I could only find this divided into two parts -- a holdover from when youtube limited the amount of time on videos much more than they do now!)
III. Presto
Now this last movement is a lot of fun. See if you can recognize a couple quotations from very famous works that he used in the middle of it. If you're really into Classical music you may even sense one of them coming up long before he comes to it. It makes me laugh every time!
