So, the roll-out of 2010 Lilith Fair dates and each city's line-up is slow. Really slow. As in, almost one at a time. Look in the dictionary under the definition of "piecemeal," and the tour is there. We reported months ago that the tour was coming to St. Louis -- and that date was confirmed earlier this week to be Friday, July 16 at the Verizon Wireless Amphitheater. The acts playing, however, are still a mystery -- mostly. Tour founder/matriarch Sarah McLachlan is on every date of the tour, of course. And now Canadian indie-popsters Metric -- who haven't been to town since a Creepy Crawl show, like, five years ago -- are also confirmed, according to their official website. The band's latest, Fantasies, was out last year. Tickets for Lilith Fair aren't on-sale yet; we'll let you know when they are.
