Mikael Åkerfeldt (guitar, vocals) and Fredrik Akesson (guitar) of the Swedish progressive metal band OPETH will attend this year's NAMM (National Association Of Music Merchants) show, which is being held January 15-18 at the Anaheim Convention Center in Anaheim, California. The signing session will take place at the PRS booth (5320, Hall B) on Saturday, January 17 from 12:30 p.m. to 1:15 p.m. The question-and-answer session will be held on Saturday at 4:30 p.m. at the PRS booth.Important: The NAMM show is **NOT** open to the public. The only attendees are NAMM member companies and their invited guests. OPETH recently released a very special digital EP called "Burden" featuring two rare B-sides, including a much-sought-after cover of ALICE IN CHAINS' "Would?" and a track previously available for a limited time only, "Mellotron Heart".
