Fri. March 12 -- Jucifer are a heavy and artistic duo from Atlanta: a mighty drummer dude plus a chick who sings like both a lost toddler and a scorched demon, and plays a guitar octave-split for added bass frequencies so it sounds like a wooly mammoth. See 'em live, but also buy their records, cuz then you can understand some of the strange and poetic stuff she's saying. Canceled for tonight: Slayer drummer Dave Lombardo's new rock trio, Philm, but they'll play with Jucifer at the Dragonfly Sunday night (see below). At Relax Bar, 5511 Hollywood Blvd., Hollywood 90028; probably late; $10.

Fri. March 12 -- Former Hanoi Rocks hair star Michael Monroe fronts a band with some latter-day Dolls etc. Monroe's set is listed as 10pm; fellow Finnish sleaze-glamsters Vains of Jenna at 9pm; The Binges at 12:15am. At the Viper Room, 8852 Sunset Blvd., West Hollywood 90069; $20; (310) 652-7869; www.viperroom.com.

Fri. March 12 -- Unpredictable but supercreative guitarist-keysman-singer Mike Keneally fronts a quartet with bassist Brian Bellar, guitarist Rick Musallam and drummer Joe Travers.

Fri. March 12 -- Light-handed but gently agitative drummer Matt Slocum leads a melodic jazz trio with pianist Josh Nelson and bassist Dan Lutz. Slocum's latest is "Portraits," featuring crisp piano from Gerald Clayton and, on a couple of cuts, really sensual sax from Walter Smith III. At Café Metropol, 923 E. Third St., downtown 90013; 8pm; $10 cover, $10 minimum; (213) 613-1537.

Sun. March 14 -- Guitarist Larry Coryell, who's been in and out every fusion door since the '60s, does his "Bombay Jazz" thing. Good idea to include an afternoon show. At Largo in the historic Coronet Theater, 366 N. La Cienega Blvd., L.A. 90048; 4pm & 7pm; $25; (310) 855-0350. www.largo-la.com.

Tues. March 16 -- Six rings of circus/rodeo extreme jazz is what you're in for with Seattle's hard-touring Reptet. At Echo Curio, 1519 Sunset Blvd., Echo Park 90026; 9pm; $5; (213) 977-1279; www.echocurio.com.

ResBox at Steve Allen Theater, 4773 Hollywood Blvd., Hollywood 90027; 8pm; $10; BYO.

Thurs. March 18 -- You remember singer Julie Christensen from post-punk days of Divine Horsemen and her own jazz throbs and some folk and Neil Youngish rock stuff, and damn, what does she not do? But she always sounds like her sensitive yet assertive self, and best of all, she's from Iowa. Christensen has been working on a new album with multi-instrumentalist Phil Parlapiano, who'll be along tonight. At Genghis Cohen, 740 N. Fairfax Ave., LA 90046; 7:45pm; $10; (323) 655-8666; www.genghiscohen.com.

Thurs.-Sat. March 18-20 -- Singer Rachelle Ferrell has a hell of an instrument, limitless improvisational chops, deep soul and, if this ain't a deficit, taste. In a just world, she'd be a big star, but she hasn't made an album in a decade. If you want to hear 8 minutes of SOMETHING, try this. At Catalina Bar & Grill, 6725 Sunset Blvd., Hollywood 90028; 8 & 10pm; $25-$40; (323) 466-2210; www.catalinajazzclub.com.
