Early in their development, drummer Mike Portnoy brought not only some great drumming but also a little bit of the spotlight to Adrenaline Mob, but the musician is now stepping away from the group as scheduling conflicts have necessitated his exit.

In a statement, Portnoy explained, "It saddens me to announce that the four upcoming shows in Latin America this month supporting Halestorm will be my last with Adrenaline Mob. Unfortunately I have scheduling conflicts that prevent me from being able to fully commit to the band's future activities at the moment. As I cannot be in two places at the same time, I don't want to hold them back and have to wait for my schedule to re-open up to resume activity."

He went on to add, "I'm very proud of what we started together and the music we made over the past two years and I wish the guys all the best in the future."

The seeds of Adrenaline Mob were formed by frontman Russell Allen and guitarist Mike Orlando, with Portnoy becoming the third member to join the group. With Disturbed on a break, the band eventually landed John Moyer to handle the bass duties.

The group has one studio album, 'Omerta,' under the belt and they followed that up with an eight-track EP titled 'Coverta' that featured the band taking on a number rock covers. At present, it is expected that Portnoy will next surface with his other band The Winery Dogs. The group will kick off a world tour in July. Dates can be found here.
