Flûte Alors! is a recorder quintet, made up of young (at least to me) musicians. But don't be fooled - their technical expertise is astounding as is their musicality. The concert was part Bach, part jazz and was held in a café (hence the beer bottle). The performance was polished and fresh at the same time.
It is particularly fun for me to hear them as I have followed some of these musicians since they were young teenagers. They have a CD coming out any day now - I'm looking forward to getting my copy.
