Les Claypool produced and engineered the record. Check out this chat with Claypool at gearwire.com (one of three audio interviews there).
The current Primus line-up is Claypool, Larry LaLonde and Jay Lane (lane was in the band early on). You can also look forward to some festival shows—Bonnaroo for instance—and a show with The Flaming Lips at Red Rocks. In the Fall the band will head out to support the record.
