CHICKENFOOT, the rock supergroup featuring former VAN HALEN singer Sammy Hagar and bassist Michael Anthony, guitarist Joe Satriani and RED HOT CHILI PEPPERS drummer Chad Smith, returned to the studio earlier this month to resume work on its sophomore album, which is expected to arrive before the end of the year. According to Satriani, the new CD "is heavier and better than the first one." He adds, "I can't wait to get it out there!"CHICKENFOOT's new album is tentatively due to be mixed in June. The CD's initial recording sessions were overseen by Mike Fraser, a Canadian producer, engineer and mixer who has previously worked with AC/DC, METALLICA and AEROSMITH. Songtitles set to appear on the album include "No Change", "Who's Next", "Astral Years" and "I Ain't Got You, I Got The Two By Blues". Hagar revealed in March that CHICKENFOOT's second album will be titled Chickenfoot IV" (Four). He said, "It's the working title but I guarantee it'll stick." He added, "We were all like, 'What are we going to call the second record? Well, 'Chickenfoot II' (Two). And we're going, 'We can't call it 'Chickenfoot II', that's too obvious.' And pretty soon [drummer] Chad Smith, I'm sure was the guy, he's going, 'Let's call it 'Chickenfoot IV'. And we all cracked up and said, 'Right on, that's it.' And we haven't talked about it since." CHICKENFOOT drummer Chad Smith recently confirmed that he won't tour with CHICKENFOOT this year in support of the band's second album due to scheduling conflicts with his main group, the RED HOT CHILI PEPPERS. CHICKENFOOT's self-titled debut disc came out in June 2009 and was certified gold for sales of more than 500,000 copies.
