Hip-hop pioneer Grandmaster Flash will headline the twelve-hour Brickside Festival at Duke Coffeehouse on April 9, the venue announced at midnight. Flash isn’t the only New York stalwart on the bill: Martin Bisi, the producer at the helm of some of the city’s most important records in the eighties and nineties, will play his own heavy solo material, too.

The rest of the diverse cast includes the folk-punk mixups of AJJ (formerly Andrew Jackson Jihad) and the hard-hitting, topically astute romps of Downtown Boys. Rising Raleigh singer ZenSoFly joins Natural Causes and Bad Friends in the local slots. Duke Coffeehouse booking manager Lauren Feilich says more acts may be added in the coming weeks.

This is the third edition of Brickside, which took a break after the 2012 edition, only to be relaunched last year. Aside from the music indoors, vendors, food trucks, and a small record fair outside allow people to roam between the cramped Coffeehouse and the roomy East Campus grounds outside.

Ticketing for Brickside requires some work, as the wristbands have to be purchased in advance at Duke Coffeehouse on select days. They go on sale Wednesday, March 23, and are available from seven p.m. until midnight. They’re also available March 24, March 28, and March 29. If any of the two hundred wristbands remain, which seems unlikely, they’ll be available at the door. Wristbands run $15 or $10 with a Duke ID.
