I love cello choirs.  I know…no surprise there.  I grew up listening to the CDs by the Yale Cello Choir under Aldo Parisot.  The lush textures and soaring tone of a mass of cellos is something almost everyone loves.  The harmonically rich music of Bach seems particularly suited to treatment by cello choir – one of the Yale CDs has both the famous d-minor Chaconne (violin) and the D-major Sarabande (cello).  There is a new CD out by the Northwestern Cello Choir and I just received my copy today.  Their performance of the Adagietto from Mahler’s 5th symphony is glorious!  If you’ve never heard the sound of a cello choir, you can find a few performances by the Yale Cello Choir on Youtube – I recommend it!
