SAN FRANCISCO--The Fratellis' two shows in the San Francisco Bay Area this week were like night and day--literally.

Late Wednesday afternoon, the Scottish buzz band opened up for the Police at the Oakland Coliseum, getting a chance to perform their much-hyped debut album to nearly 50,000 people, most of whom were preoccupied with beer and bathroom queues.

But last night at the Fillmore across the bay, it was an entirely different affair. Sure the crowd was more than 41 times smaller, but the trio of Barry, Jon, and Mince Fratelli had its rapt attention for the duration of the one-hour set.

The Fratellis play the kind of raucous, terribly fun rock and roll you'd hear in a dank pub, much like Minneapolis-based The Hold Steady, although--at least on this night--without the on stage shots and beer can shotguns.

The Glasgow trio got a surge of momentum earlier this year when its song "Flathead" was picked to score the latest iPod silhouette ad, an endorsement that often brings both a critical and popular boost.

That boost was vivid last night, as fans roared after every song, even the more obscure ones, from Costello Music, the band's crafty yet boisterous debut album. "For the Girl" was a pure, unadulterated tale of young love, set to a speedy tempo and chock full of delightfully catchy hooks, including plenty of "la-la-las."

"Flathead" drew the biggest applause of course, as did "Chelsea Dagger," the album's second single off Costello Music. It was driven by a rock-radio-friendly beat and even a party-starting "deh-deh-deh-deh-doo-doo-doo" chorus, which drummer Mince Fratelli (Gordon McRory) charged through with gusto.

For one night, the Fillmore was transformed into an uproarious Glasgow pub, and this buzz band threw its fans quite a party.
