Sub Pop Records will celebrate its 20th anniversary with a 2-day party at Seattle’s Marymoor Park this summer, with many of the bands that have collaborated with the label throughout its two decades of existence performing on this occasion.

A July 12-13 party is being planned out by legendary Seattle record label Sub Pop, which celebrates 20 years of existence. Billboard.com reports that several groups will reunite or break long hiatuses in order to perform at the event. Among them are Green River, Red Red Meat, the Fluid, Beachwood Sparks and Seaweed.

Current label acts confirmed to appear include Fleet Foxes, Flight of the Conchords, Foals, Grand Archives, the Helio Sequence, Iron & Wine, Kinski, Low, Mudhoney, No Age, Wolf Parade, Pissed Jeans and the Ruby Suns.

The lineup does not end here, as additional bands are to be added to the bill. Tickets go on sale April 26.

Those celebrating with the indie label will also enjoy a comedy night, which will be held July 11 at the Moore Theatre. It will feature Patton Oswalt, Eugene Mirman, Todd Barry and other guests.

The indie label is well known for first signing Nirvana, Soundgarden, Mudhoney and many other bands from the local Seattle music scene. Jeff Ament, who played in Green River with Stone Gossard before they left to form Mother Love Bone and then Pearl Jam, told Billboard that the show is a chance for him to reconnect with Mark Arm and Steve Turner, who went on to form Mudhoney.

 “There's been a few emails exchanged and a few jokes about how we'll get our hair that big and long again,” he told Billboard.com. “We might all have to go in for weaves. If we got together and wrote a couple of songs and put out a single, that'd be more important to me than playing a show; just getting in a room together.”
