Philadelphia hardcore heroes Kid Dynamite will reunite Aug. 15 as part of the weekend-long This is Hardcore festival at the Starlight Ballroom (460 N. 9th). Kid Dynamite last performed in August 2005 at CBGB's in a series of shows to raise money to save the legendary New York club, now a John Varvatos store.

This is Hardcore also features Thursday singer Geoff Rickly fronting for an Ink & Dagger reunion set. The band's singer, Sean McCabe, died in 2000 at age 27. Dagger's money from the onetime show and T-shirt sales will benefit Maks Zielanski, son of Crud Is a Cult and Flagman member Ed Zielanski, who has a rare childhood cancer.

Cro-Mags, Sheer Terror and Killing Time are among the several dozen bands who will perform throughout the weekend. Tickets are almost sold out, but will be available starting at 11 a.m. today at AKA Music (27 N. 2nd). Tickets ($25-$28 or $70 for a festival pass) are cash only.
