The release date of Mike Watt [ tickets ]'s "The Secondman's Middle Stand" has been pushed back to Aug. 24.

"There just wasn't enough time to get things together enough," Watt wrote on his website. "Like my product manager (who I respect much), Peter Fletcher, said: 'It's been a while since your last record and we should set this up right,' and I couldn't agree more."

Watt, who was a founding member of Southern California punk rockers Minutemen, has described the new album as his "illness piece," documenting his bout with a painful intestinal abscess a few years back.
