Mike Portnoy was already famous for this during his Dream Theater tenure; he's since made a brief appearance in Avenged Sevenfold, completed a fourth Transatlantic album, guested on Bigelf's most recent album, filled in on Stone Sour's Brazilian tour, and formed Flying Colors and Adrenaline Mob. So far, it seems both the Winery Dogs and Flying Colors are headed for a second album, which for Portnoy probably counts as a boring year.
Billy Sheehan is not quite Portnoy's match, but between solo work, session play, jazz-fusion project Niacin, and the occasional Talas and Mr. Big reunions it's a wonder he has any free time at all.
Fittingly, Portnoy and Sheehan are also half of a Progressive Metal supergroup (along with keyboardist Derek Sherinan and guitarist Tony MacAlpine) whose reunion briefly interrupted the tour.
Call Back: The live set usually features songs from Sheehan and Kotzen's past bands, with Talas' Shy Boy and Poison's Stand being the most common. Kotzen-penned Shine (from their shared time in Mr. Big) sometimes turns up.
Performance Video: Four videos, all four showing the band playing without a real narrative. Time Machine changes it up a bit with footage of the band playing the song at a show in Japan, ironically enough.
