While Keith Richards finally settled on Island for his debut solo album, Mick Jagger's putting the finishing touches on his second solo album for Columbia. Look for a fall release and, in all probability, a solo tour, which would be a first for Jagger. As for the band's other guitarist, Ron Wood, he's been spending many of those awkward periods surrounding the Stones' occasional tours and albums over the last 10 years painting. Wood's first-ever show will go up at the Govinda Gallery in Georgetown in December and Harper & Row will bring out a book of his work around the same time. Wood will be at a book-signing at Govinda the day after opening night, and there's a good possibility of a local concert date -- solo, natch.

Pink Floyd, which hasn't performed in five years, will be playing at Capital Centre Oct. 18 and 19; Roger Waters, one of the band's founding members, will bring his new band -- and a continuing legal tussle over the Floyd name -- to Cap Centre Aug. 30. So who's in the road Floyd? Guitarist David Gilmour, drummer Nick Mason and keyboard player Rick Wright, who left the group several years back and has returned for the tour and for an as-yet-untitled album to be released in late September (Waters' latest solo album, "Radio K.A.O.S.," hit the streets a few weeks back). Meanwhile, "Dark Side of the Moon," recorded when everybody was apparently still talking to each other, just entered its 688th week on Billboard's charts, with every week extending the group's record for longevity there.

And, just to prove that international trends can have a local angle, guitarist Jim Thackery has officially departed Washington's Nighthawks, who "broke up" last year -- except they still keep playing together on "special occasions" (admittedly, they called their last concert "Farewell -- For Now"). Thackery, who was with the Hawks for 15 years, is now leading his own group, The Assassins. The remaining Nighthawks will continue playing with guests like Elvin Bishop, Bob Margolin and Jimmy Hall of Wet Willie, but are looking for a new full-time guitarist and vocalist. A recording made at last July's Carter Barron farewell will be out early in 1988, but another album recorded "Live in Europe" just a few days later will be hitting the streets in the fall. Already out overseas, it contains new songs by Steve Earle and Keith Sykes, and, following another commercial trend, both collections will feature extra cuts on their CD versions.

Reunion Time

If it looks like the Rolling Stones have broken up, there are some reunions of note. The Doobie Brothers, who reunited earlier this year for a series of West Coast and midwestern benefit concerts (with a final concert in Moscow on July 4), apparently liked what they heard. They'll soon be recording again, and will follow the album with a major tour (though without Michael McDonald, who continues to pursue his solo career). Lynyrd Skynyrd, the southern rock band that fell apart after a 1977 plane crash that took the lives of singer Ronnie Van Zant and guitarist Steven Gaines, will reunite at Charlie Daniels' Volunteer Jam in Nashville in early September before embarking on a 25-city tour. MCA will put out a new album containing previously unreleased tracks.

Film Notes

Prince is reportedly putting the finishing touches on his next film, a concert affair shot during his recent European tour (his current video for "You've Got the Look" looks to be an excerpt). Prince has apparently given up on the contrived "sophisticated comedy" that made "Under the Cherry Moon" one of last year's biggest bombs. His ex-Revolutionaries, Wendy and Lisa, are about to release their first solo album on Columbia, with production duties shared with the Revolution's old drummer, Bobby Z.

Penelope Spheeris, whose 1981 rockumentary "The Decline ... of Western Civilization" was a harrowing but sympathetic overview of Los Angeles' punk community, is planning a follow-up: "The Decline ... Part II: The Metal Years." The film will take in the various "schools" of metal -- traditional bands like Deep Purple and Black Sabbath, glam-ers like Mo tley Cru e and Faster Pussycat, and speed merchants like Megadeth and Overkill. Despite the dismal showing of Alex Cox's "Straight to Hell," Spheeris will soon release another of her fictional works, a "punk western" called "Dudes," before embarking on an Ozzy Osbourne vehicle titled "Seeing Stars." Osbourne, who was quite funny as an antirock crusader in the heavy metal film "Trick or Treat," will portray a burned-out '70s rocker who finances his comeback with a loan from the Mafia and somehow ends up on the run with two girls. Meanwhile, rumors are flying that Bob Dylan's "Hearts on Fire" film -- also having to do with a '70s rock 'n' roll hero's comeback -- is in such bad shape that it's not going to make its fall release.
