Saturday at the Rock and Roll Hotel. Dr. Dog with The Teeth and Hoots and Hellmouth. $12. Doors at 8:30, Music at 9:30.

Depending on the circles you run in, Dr. Dog are either busy working a tired formula of lo-fi and late-period Beatles nostalgia or are one of a host of Philly groups artfully resurrecting the heady psych-pop era of the late 60s and early 70s.

Both camps need to do themselves a favor and catch the Dr. Dog live show, where the lo-fi becomes a warm, charming fuzz and the squeaky harmonies on record are revealed more as the signs of sheer enthusiasm than vocal flaws. And if Beatles references are your thing, you’ll definitely get a kick out of these guys – there are those half-lazy tom fills, melodic slide solos, and ringing, soaring harmonies. On their latest full–length, We All Belong, they’re no less retro-minded, but they’ve ditched the 8 track for a 24 track, and the songs ring with a new clarity and grandeur. “Worst Trip” quite overtly steals its chorus from the Beach Boys, but then a messy sprawl gives way to a surprising Thin Lizzy guitar figure. And “Alaska” sounds like a distant cousin of “Bold as Love”.

They’ve garnered comparisons to Pavement and Guided by Voices, too, which doesn’t give you a good feel for their sound so much as their aesthetic. Like both bands, they’re adept at writing short pop fragments and putting in a context where they work as a whole, but stylistically you’ll hear more in common with neighbors Capitol Years, The Teeth (who open up Saturday), and the more direct Elephant 6 groups. Which, naturally, brings us back to the Beatles. But frankly, few bands have mined Abbey Road and White Album-era Fab Four so fruitfully, teasing out the quirk, nuance, and true classic rock feel of those records better than anyone. If you’ve ever been exhilarated by the idea of those classic albums being played live, join us at the Rock and Roll Hotel on Saturday.
