Wolfgang tweeted yesterday: "Holy shit! An abrupt change of plans has left me playing bass with @MarkTremonti tomorrow! I've got some tunes to learn!" Tremonti tweeted: "Due to personal reasons, [regular TREMONTI bassist] Brian Marshall won't be with us on this tour. On a lighter note the amazing @WolfVanHalen will be joining us!"For a list of upcoming TREMONTI tour dates, go to this location. Tremonti, who has been friends with Wolfgang Van Halen since CREED opened for VAN HALEN for a couple of shows in 1998, told Ross Ford, a morning radio show host on Colorado's 94.3 KILO, that Eddie Van Halen's son invited Tremonti to VAN HALEN's 5150 studio last year to watch Eddie, Wolfgang and drummer Alex Van Halen rehearse. During the visit, Mark got to hear VAN HALEN perform the entire "A Different Kind Of Truth" album months before its eventual release. "It was amazing to see them do it right in front of me," Mark told Free Gotham. "I was thinking, how many people in the world get to do this?"
