NIRVANA WILL HIT the streets Dec. 15 with “Incesticide,” a collection of unreleased songs, B-sides and demos. The DGC album includes music from two BBC sessions recorded in 1990 and 1991 (featuring songs “Turnaround” and “Son of a Gun”), B-sides “Even in His Youth” and “Aneurysm,” and some old demos from the band’s Sub Pop Records days.A punk version of the song “Polly” from the Seattle three-piece’s 4 -million-selling debut “Nevermind” is also included. Some of the songs were previously released in Japan and Australia by DGC in EP form under the name “Hormoaning.” According to management, the band (vocalist/guitarist Kurt Cobain, bassist Chris Novoselic and drummer David Grohl) has finished writing material for its next studio album in Seattle, Butch Vig returning as producer. A spring or summer 1993 release is anticipated. MICK FLEETWOOD MADE his debut in music 25 years ago in August, playing at Fleetwood Mac’s first gig, the Windsor Jazz Festival. You might say he’s come full circle. This Wednesday, after years of playing the world’s largest arenas and recording one of the biggest-selling albums of all time, Fleetwood appears at a private industry party at the Upside Down Club (formerly the China Club), a venue that normally accommodates artists a bit further south on the career line. Not that Fleetwood minds. In fact, he views his stint with Capricorn recording artists the Zoo as putting him back in touch with the reasons he got involved in music. “People forget, I’ve been doing this on and off for years with the Zoo,” the soft-spoken drummer says. “I much prefer bus travel, actually. I would have preferred the Mac to do that. Everyone was always, ‘get the plane,’ and I’m not complaining, but it cost one hell of a lot of money.” The Zoo is a long-running Fleetwood side project, although it’s never been as permanent as it is now, with Fleetwood Mac basically a recording unit. Composed of vocalist Bekka Bramlett (daughter of R&B duo Delaney & Bonnie), guitarists Billy Thorpe and Gregg Wright, bassist Tom Lilly and keyboardist Brett Tuggle, the unit is out in support of “Shakin’ the Cage,” its Capricorn debut. “The essence of what has become this band is very riff-oriented and that’s how Fleetwood Mac started,” Fleetwood says. “It’s a real sense of players who know when not to play. There are places where someone can stretch out, but it’s not a jam band.” Meanwhile, there’s also the matter of Fleetwood’s old project. At Christmas, Fleetwood Mac fans can look for a greatest hits collection on Warner Bros. that will contain at least three new tracks. But a full-fledged reunion will not be part of that package–guitarist Lindsey Buckingham backed out at the last moment, citing “personal pressures,” according to Fleetwood. THE LAST DOOBIE BROS. concert featuring all 12 past and present band members took place last night at the Greek Theatre, a benefit for the family of terminally ill band member Bobby LaKind. The beneficiary of the monies raised at the shows is the LaKind Children’s Trust, a fund set up by the band to ensure the future well-being of LaKind’s family. The percussionist-vocalist is suffering from inoperable cancer. The 22-year-old group has no plans to continue with this massive roadshow, although it’s likely the Doobie Bros. will still exist in some form. A San Francisco area show scheduled for tonight will mark the 12-member-unit’s final performance. Last night’s grouping was crowned by the appearance of lead vocalist/keyboardist Michael McDonald, who hadn’t appeared with the Doobies since a series of benefit reunions in 1987. THE RAMONES: Unvaryingly simple and straight to the point, three-chord, high-speed pop. The band has been working the same formula with only slight changes since 1976, and has more or less played the same songs in the same order for the last 10 years. That suits the fans just fine, which is why the Ramones can still sell out the 4,000-capacity Hollywood Palladium for three nights during a recession (as they did last week), and underlines the reasons why the group’s new label, RadioActive (run by band manager Gary Kurfirst), has a massive campaign under way to sell these grizzled vets, even going so far as to send out customized Ramones leather jackets to key radio and press and recruiting Nirvana’s video director. So far, it hasn’t worked. Despite glowing reviews, the band’s “Mondo Bizarro” entered the Billboard 200 at 190 and fell out a week later. The single, “Poison Heart,” fared reasonably well on alternative radio, but at Top 40, nada. At the Palladium last week, the Ramones front-loaded the “hits” like “I Wanna Be Sedated” and “Blitzkreig Bop” (now part of a Budweiser commercial), then wedged in the new material, encasing it in a heartfelt stage speech by lead singer Joey Ramone. Best of all was a guest appearance by Doors guitarist Robby Krieger on “Take It as It Comes,” the Doors oldie. Krieger added a welcome dose of lead guitar to the endless strumming of Johnny Ramone.
