Video footage of drummer Mike Portnoy (ADRENALINE MOB, FLYING COLORS, THE WINERY DOGS, DREAM THEATER, AVENGED SEVENFOLD) talking about Samson drum gear and microphones used in his home studio can be seen below.ADRENALINE MOB released "Covertá", an eight-track EP featuring cover versions of some of the group's favorite songs, on March 12. Longtime fans of Portnoy are aware of the multiple cover CDs he has released with DREAM THEATER and with Neal Morse. "Covertá" is the first CD of covers recorded by ADRENALINE MOB. Portnoy, who co-founded DREAM THEATER more than 20 years ago, abruptly quit the band in September 2010 while on tour with AVENGED SEVENFOLD. He has since been replaced by Mike Mangini (ANNIHILATOR, EXTREME, JAMES LABRIE, STEVE VAI). Portnoy played on AVENGED SEVENFOLD's latest album, "Nightmare", following the death of that band's drummer, Jimmy "The Rev" Sullivan, and toured with them for the entire second half of 2010.
