Trey Anastasio: What's Happening August 5, 2005 - The Plain Dealer By Annie Zaleski Think Trey Anastasio is creatively adrift now that the legendary jam band he fronted, Phish, is on a permanent vacation? Think again. The one-time vocalist has been cultivating a solo career for much of the last decade, starting with 1996's "Surrender to the Air," an adventure in free-jazz freakouts featuring Sun Ra saxophonist Marshall Allen. After the experimental quirkiness of Oysterhead - his trio with Les Claypool and Stewart Copeland - Anastasio unfurled some coffeehouse-beatnik grooves on his jazz- and prog-inflected self-titled 2002 disc and added orchestral loveliness for good measure on 2004's instrumental album, "Seis de Mayo."
