Chris Cornell has left the new, as-yet-unnamed band he formed with Rage Against The Machine's Tom Morello, Brad Wilk, and Tim Commerford, according to reports. The surprising news comes just days after the group was touted to make its live debut as part of this summer's Ozzfest tour. A tour spokesperson refused comment on the reports; management representatives did not return calls.

It is not known why the former Soundgarden frontman chose to exit the new band, as recording sessions for its planned Epic debut album have been shrouded in secrecy from the beginning. Reports suggest that the recently completed album will still be released this summer. Other unconfirmed reports said the band had settled on the moniker Civilian, but had to forgo it after discovering another act already existed with the same name.

By all accounts, the project began with unbridled enthusiasm from all members, particularly Morello and company, who were still reeling from vocalist Zack de la Rocha's October 2000 departure from Rage. Morello told Billboard at the 2001 Grammys that initial jam sessions with Cornell were "downright groundbreaking" and "off the scale." He added that the foursome was "just enjoying making music again. That's all we're concerned with right now."

Cornell has kept an extremely low profile since his 1999 A&M solo debut, "Euphoria Morning," which opened at No. 18 on The Billboard and has sold 324,000 copies in the U.S. to date, according to SoundScan.
