One of the US's most legendary indie labels, Sub Pop's back catalogue includes Bleach by Nirvana, Sonic Youth, The Postal Service and Mudhoney among many others.
Sub Pop's A&R head honcho Tony Kiewel told Rolling Stone that all future albums from the label will automatically be available for Rock Band.
