Uprising, I Surrender join indie arm of Sony BMG.

RED Distribution has added two rock-focused indies to its roster of third-party labels. Effective immediately, the independent arm of Sony BMG will handle releases from Southern California’s Uprising Records and Brooklyn-based I Surrender Records.

Uprising releases previously went through Koch Entertainment Distribution, and I Surrender was without a formal distributor, releasing its albums through online outlets such as SmartPunk.

Uprising has released albums from Fall Out Boy and Stretch Arm Strong, and will soon be launching an urban division. Upcoming releases include albums from punk act Red Knife Lottery and rappers Taj Mahal and Tragedy Khadafi.

I Surrender has released albums from rock artists Stars Hide Fire, the Westminster Abbey and Vice Versa. On Sept. 19, the label will issue the debut from Valencia, “This Could Be a Possibility.”
