GZR, the band featuring bassist Geezer Butler, appear to be back in some sort of action.

Six years after the release of their last album, 2005’s Ohmwork, GZR are involved in writing new material.  Where this leads, though, remains to be seen.

It is known that drummer Chad Smith (not the Red Hot Chili Peppers man)В is involved; he appeared on the last record. Guitarist Pedro Howse and vocalist Chad Brown are also contributing.

GZR released four albums between 1995 and 2005.
