"World of Drum & Bass" is an annual tour intermingling British DJs and artists with local talent at specialized events. This year, DJs Ivry and Sharp from S.F. club night "Compression" and Tone and Paul Hemming of host venue Temple will spin, and S.F.'s Audio Angel will sing alongside performances by Canada's Greenlaw, U.K. MC Killa Kela, and DJs Bryan G, Fabio, Simon Bassline Smith, SS, and others. With such a large lineup spread across three rooms, it might be hard to follow who is playing when, and while microstyles of the genre will vary, don't expect any chillout music on Friday, March 21, when the tour hits Temple at 9 p.m. Admission is $20; call 978-9953 or visit www.templesf.com for more info. — Tamara Palmer
Watching Medusa won't turn audiences to stone, but she is a stone-cold rapper — and one of L.A.'s best-kept secrets. With a fierce look and a sharp way with words, she embodies fearlessness, naming a recent single "This Pussy's a Gangsta." She possesses a certain confidence that comes only after years in the game. Medusa ruled South Central's storied Good Life Cafe, the '90s open-mike night that nurtured the careers of influential L.A. hip-hop artists like Freestyle Fellowship and Jurassic 5 and spawned a documentary. Medusa performs live on Friday, March 21, at Sisterz of the Underground's Seven-Year Anniversary party at Club Six at 9 p.m. Admission is $7-$10; call 863-1221 or visit www.clubsix1.com for more info. — T.P.
