The Winery Dogs consists of Richie Kotzen on guitar, keyboard and vocals, Billy Sheehan on bass and backing vocals and Mike Portnoy on drums and backing vocals. If you started adding together all the studio albums, EPs, collaborations, compilations, solo albums, and guest appearances these guys have made then you would run out of fingers and toes pretty quick. You can count over 100 without even getting to many of their more obscure releases, and that isn't even counting live albums.
Mike Portnoy is, of course, the former drummer of Dream Theater who surprised pretty much everybody when he bailed out to make a full time commitment with Avenged Sevenfold, though they booted him shortly after that. Since then he has released a few albums with his various other supergroups, and the results have varied.
Billy Sheehan is possibly the best living rock bass player in the world, and has worked with David Lee Roth, Mr. Big and Steve Vai.
Richie Kotzen was first discovered by Shrapnel Records and started his solo career, but was snatched up pretty quick by Poison. His stint with Poison was cut short when it was discovered that he was having an affair with Rikki Rockett's fiancé. Richie went on to continue with his successful solo career, several other projects, and also replaced Paul Gilbert in Mr. Big. These guys have all pretty much proved their mettle a hundred times over, and did we mention they'll be blowing the roof off our joint this memorial day?
