RESTLESS RECORDS recording artist and former Lone Justice bassist Marvin Etzioni has already pumped out his second album of 1992, “Bone,” a full-band followup to his critically acclaimed acoustic album”The Mandolin Man.” It’s all part of a game plan to release several discs a year through the Los Angeles-based independent label.“It’s not that I’m saying, ‘OK, great, I’ve got another 10 songs, let’s put out a record,’ ” Etzioni says. “But I have a lot of songs and I’m always writing.” In addition to his own work, Etzioni has found time to co-write for former Lone Justice signer Maria McKee, and plays on her upcoming Geffen album. The appearance with McKee hasn’t slowed Etzioni down a bit. He’s already recording “Big Mono Sex Doctor,” a new album where he plays all the instruments. Four tracks have already been cut, with plans for an early 1993 release. Etzioni will appear as part of a special Restless Records showcase tomorrow at the Troubador. Also appearing is Seattle-based trio Sister Psychic and Santa Barbara’s Cinderblock. The all-ages show begins at 8:30 p.m. FORMER NEW YORK DOLLS bassist Arthur Kane was attacked in front of his West Hollywood home this summer and required hospitalization and an extended rehab. Like so many other poor Americans, he was minus health insurance and needed a bailout. Help came from various L.A. members of the New York/Glam/’70s axis Sept. 12 at the Troubador, raising approximately $ 5,000 for Kane, according to benefit spokeswoman Astrid Young. Local rockers Motorcycle Boy and former New York Doll Sylvain Sylvain teamed with ex-Blondie guitarist Frank Infante to open the show. Sylvain’s versions of Dolls classics like “Trash” and “Pills” brought down the house. Following Sylvain was Dramarama, Pixies drummer Dave Lovering sitting in, and they also presented a bit of the Dolls past with “Private World,” which was Kane’s sole contribution to that band’s repertoire. The highpoint was the surprise appearance of Paul Rodgers and Jason Bonham, who performed a trio of blues gems. Rodgers is currently assembling a tribute album to Muddy Waters, and he and Bonham cruised through “Hootchie Kootchie Man” and “The Hunter” like the old pros they are. The expected headliners, Chequered Past, never showed, but no one missed their reunion, as no one cared about them the first time around. GERARDO’S NEW Interscope album, “Dos,” finds the Spanglish rapper with the washboard stomach prepared to show that he’s less of a pop star, more of a rapper. “You can tell I’ve grown as an artist, rapper and writer,” he says. “I took a lot of flack last time. But now they’ll realize I can do it. I have a lot of friends who are into underground music, and they go, ‘damn, you got a lot better.’ “ While the videos for Gerardo’s hit “Rico Suave” promised to propel the former actor back toward some big-screen roles, the hoped-for jobs were killed by his extensive touring schedule. “There were a lot of projects I was supposed to do between albums, but then we went to Europe and Japan, and there wasn’t any time in between.” Gerardo also reported that a $ 10 million lawsuit by his alleged former partner over credit and compensation on his first album, “Mo’ Ritmo,” is close to being settled. SONGWRITERS EXPO 16 will be held Saturday, Oct. 31, and Sunday, Nov. 1, at the Los Angeles Airport Sheraton Hotel, designed to help aspiring and professional songwriters learn and refine their craft.

CAROLE KING was last on the charts in 1990 when her Capitol disc “City Streets” hit the top 20 of the Billboard 200. Although it’s hard to imagine the artist who shaped the sounds and standards of the songwriting ’70s with her Ode/CBS disc “Tapestry” being without a label deal, such is the case. Since being dropped by Capitol, the artist has been on a number of soundtracks, the most recent of which is “Now and Forever” from Columbia Pictures’ “A League of Their Own.” The song has been holding steady of the Adult Contemporary charts. King has also recorded her own album, titled “Color of Dreams,” and is said to be close to a deal. A tour, set for February launch, will support the new album, . Joining King on her album are guitarist Slash and keyboardist Ted Andreadis of Guns ‘N Roses. Andreadis was in King’s band and played on the “City Streets” disc before being recruited by Axl Rose. King will also have a small part in the James L. Brooks film “I’ll Do Anything,” under way for Columbia Pictures, and will also contribute music to the film, slated for fall ’93 release.
