Halloween is one of those holidays when it's OK to really get into a cover band, and this year the Black Sabbath tribute band HAND OF DOOM makes it easy. Featuring members of Hawks, Blame Game, Vera Fang and others, the robbed soothsayers of the apocalypse peel through an hour-long set of your favorite Sabbath riffs, complete with costumes, the promise of onstage drug use, booze and various other satanic debaucheries. Who Killed Marilyn?, a Misfits tribute band featuring members of Vera Fang, Facehugger and Thy Mighty Contract, tear through 12 Glenn Danzig classics to open the black mass. $5. 10 p.m. 529, 529 Flat Shoals Ave. 404-228-6769. www.529atl.com.
