As rumored last night, The Vaselines and Eric’s Trip (and Les Thugs, too) have been added to the Sub Pop 20th anniversary party in Seattle July 12 and 13, and there’s still “more to be added soon.” Also, for those of you wondering where Tad is, there’s also a news-to-me show featuring the Gutter Twins (Mark Lanegan and Greg Dulli!) and the Brothers of the Sonic Cloth (Tad!!!) the night of July 12 at the Showbox. The show will be the Vaselines’ first Stateside show ever, and some rabble-rouser in our comments is saying that they’re going to play New York, too?! Oooh. Full lineup (including the roster for the Friday night comedy show) after the jump. [SubPop.com]
