UPDATE - 6/15@1:31PM: They will be in LA too.

The Foo Fighters will be hosting 2 tribute concerts for the late Taylor Hawkins - the beloved Foos drummer who tragically passed away earlier this year. The first show will take place at London's Wembley Stadium on September 3rd and the second show at Los Angeles' Kia Forum on September 27th. Earlier today the Foos announced some of the guests for the London show, and Rush's Geddy Lee and Alex Lifeson will both participate, but it's not clear in what capacity at this time. Other guests on the London bill include Chris Chaney, Stewart Copeland, Liam Gallagher, Omar Hakim, Josh Homme, Chrissie Hynde, Brian May, Mark Ronson, Supergrass, Roger Taylor, Rufus Taylor, Wolfgang Van Halen and Chevy Metal, as well as a special appearance from comedian Dave Chappelle. Tickets will be available starting Friday, June 17th at 9:00 AM local time, and proceeds will benefit charities in both the UK and the US chosen by the Hawkins family. You can get tickets to the London show here, and the Los Angeles show here. More details as they become available.
