On June 30, Derek Simmons-Tobias of Examiner.com conducted an interview with guitarist Bill Kelliher of Atlanta progressive metallersMASTODON at the Mountain View, California stop of this summer'sRockstar Energy Drink Mayhem Festival. You can now watch the chat below. Asked about the progress of the songwriting sessions for MASTODON's follow-up to 2011's "The Hunter", Kelliher said: "Before we left for the European tour, which was prior to this, we got into a studio with a producer. We started just putting ideas down on tape, so to speak. We have about 25 to 30 songs that are ready for the new record. We're obviously not gonna use all 30 of them, but we're in a much better place than we've ever been as far as being prepared during pre-production for an album. We'd like to get the record finished by the end of the year and have it out as soon as Christmas and all the holidays are over with — maybe, like, March or April, it would be great to have the new record out and then do a brand new tour on some new music."
