Here's a happy accident; earlier I grabbed this BIS disc and imported it, mindlessly assuming there was a Takemitsu work on it (I have visually similar BIS compilations I guess) and after realized there isn't. This is a great cd however, and I didn't remember Eberhard Werdin's "Concertino for Flute and Guitar with String Orchestra" at all, which is the first composition on the album and a very good one at that. It has a certain Hindemithian feel here and there, especially in the first movement; the 2nd and 3rd movements that follow are also beautiful, with the flute and guitar dancing together and quite the Spanish atmosphere in the 3rd movement, so very graceful, and even castanets join in the merriment (I instantly thought of the Boccherini Quintets, not to mention the sound world of Joaquin Rodrigo).
I was happy to (re)discover the Concertino! The other works I particularly enjoy are Gunnar Hahn's "Suite for Flute in Folk Style" which is inspired by Swedish folk music, Castelnuovo-Tedesco's "Sonatina for Flute and Guitar", and the wonderful Jacques Ibert, his "Entr'acte pour Flute and Guitar", 3 minutes and 18 seconds of pure charm with a dash of Iberian flavor. Enjoy!
