When: September 4th-6th
Where: Seattle, Washington
Why Go: The U.S. summer festival explosion is a rather recent phenomenon, but Seattle's Bumbershoot has existed in one form or another for four decades. 2015's lineup hasn't been announced yet, but last year's ranged from Elvis Costello and a tribute to Big Star's Third to hip-hop royalty Wu-Tang Clan. It showcased funk legends Bobby Womack and Bootsy Collins as well as up-and-coming rappers like Schoolboy Q and Danny Brown.
Must-See Acts: Lineup to be announced.
