This Philadelphia garage band is named after Russ Meyer's pseudo-documentary, and like their namesake -- a 1966 look at bare-breasted women worldwide -- they gleefully step on, over and way the hell past the boundaries of good taste. The band raunchily tears through tracks like "Panty Sniffer" and "Think with Your Hands" (further pursuing a theme from their first album, Fifty-Thousand Dollar Hand Job) with a sound that is as dirty and leering as the lyrics it supports. It's juvenile, and full of the sniggering smart-ass humor you last heard in the back row of high school homeroom, but it's also seriously rocking and really, really fun.

If you're playing along with our garage rock bingo game at home, you'll find Mondo Topless in the Merseybeat-influenced column, fourth row down ("Includes organ player", just after "Female lead singer", "Blues duo" and "No bass player"). Sam Steinig's vintage Vox Continental organ is, perhaps, the band's defining feature, squealing and swirling and surging under their manic beat. The Vox Continental was one of the earliest portable organs, and its bare bones sound (no bass, limited vibrato) was the hockey-rink heart of songs by the Monkees ("I'm a Believer"), Paul Revere and the Raiders and the Dave Clark Five. If you've ever heard the high-toned arpeggios beneath Eric Burdon's guitar in the Animals' "House of the Rising Sun", you've heard a Vox Continental at its best, and Steinig pays tribute to the Animals' keyboardist Alan Price in a cover of "I'm Crying". It's a frantic romp through every decade's garage land -- Mondo Topless borrowing from the Animals, the Animals borrowing from Bo Diddley, and Bo -- well, who knows where he got that guitar line, but I bet he didn't make it up.

Among the original tracks, "Think with your Hands" is the standout -- John Loxterman's snaky, sinister bass line percolating under Kris Alu's surf-guitar accents and underlying Steinig's creepy, insinuating vocals. "Horsefeathers" is also quite good, built on a very simple, punishing drum line with a rhythmic stop-and-start verse and a shouted chorus of "Horsefeathers ... You said it again." It's bare, stripped-down rock and roll at its essence -- not a lick of organ here. "Anytime" puts the same insistent rhythm to work in the bass line, tops it with a syrupy wash of organ, and backs the vocals down to a sweeter, mildly poppier level.

No garage band worth its salt can leave the Stooges alone, so Go Fast! closes with that band's "Loose", from the Funhouse album. It's a reasonably good cover, but listening to the two side by side just makes it obvious where current garage rock diverges from the old stuff. Iggy sings like he's just back from sabbatical in the ninth circle of hell, rocking like a lost soul who knows he's headed back as soon as the song ends. Mondo Topless, by contrast, sounds like they're closing out the coolest keg party you've ever been to, and maybe afterwards will grab a few pancakes at the all-night diner. They just can't wipe the grins off their faces, and while that may keep them from ever being as demon-ridden brilliant as the Stooges, it does make Go Fast! a slamming good time.
