Independent record stores have been on the endangered-species list for many years, so much respect is due to Chaz’s Bull City Records – which has somehow hung in there for more than a decade and become a Durham institution in the process. And this weekend, the store marks its 11-year anniversary (Why celebrate 11 years? Because why not?) with an impressive multiple-night anniversary party.

Friday’s show features Dirty Little Heaters and Dry Heathens, among others, at Durham’s Pinhook; and Saturday’s headline event is Saturday at Ponysaurus Brewing Co. with a lineup including Superchunk’s first local show in eons, hardcore old-timers Pipe and Brad Cook and friends (including William Tyler, and Cook’s old Megafaun bandmates). Tickets range from $15-$65, and kids 12 and under get in free to the Saturday show. See bullcityrecords.com for details.
