LADY SOVEREIGN AT THE ECHO: She made tons of headlines back in the mid-aughts with her take on British grime-style hip-hop. Now Lady S. is doing a mini-jaunt through the U.S. ahead of "Jigsaw," her new album due in April. LA's only one of three cities -- NYC and Chicago being the other two -- so this is definitely a show to catch. Friday, February 6, 9PM. The Echo, 1822 Sunset Boulevard, Los Angeles. 213-413-8200
CEAIT FESTIVAL OPENS AT REDCAT: The far reaches of sound are merrily, boldy traversed as artists unleash a beautiful range of audible treats at this two-day hear-it happening. Marina Rosenfeld is arriving with her phonographic speaker, which rotates while emitting electroacoustic vibeage; other experimental works, instruments and ideas from forward-thinkers will take front and center. Or should we say, a place right next to our ears and minds. Roy and Edna Disney/CALARTS Theater, 631 W. Second Street, Los Angeles. 213-237-2800
MORE FRIDAY, FEBRUARY 6 GOINGS-ON: Former "Saturday Night Live" funny guy Kevin Nealon (we were never sure if he was Hans or Franz) is at the Brea Improv; the Little River Band is still "Reminiscing" at the Canyon Club; and the Master Musicians of Jajouka play at Royce Hall.
