Loomis, with its peppily aggressive attack and its bare-bones three-man lineup, comes on with the energy and immediacy of one of Q101's emo-charged punk-pop outfits. But the heart of their songs is in something more mature; a little subtler and smarter, and a little more musically proficient.

Just a few licks into their all-too-brief set at Nevin's in Evanston on Saturday night, March 6, the talented singer-guitarist Tom Valenzano was merging his slick licks with Beatlesque harmonies and memorable tunes that have earned comparisons to acts as diverse as (on the one hand) the Beatles and Elvis Costello and (on the other) Jimmy Eat World and the Smoking Popes.

The band flips through different kinds of catchiness like a couch potato flips through cable channels, from '60s Brit Pop jangling with muscular punk-pop licks, to a more Neil Finn-like brand of Beatlocity with moving mid-tempo melodies and smart impressionistic lyrics. Many of these different flavored candies were on display at Nevin's show -- actually, for my money not enough of them. The band confessed to skipping a couple of numbers inadvertently from their set list, which has been whittled down over their years together to a portfolio of about 22 songs, 13 of which ended up on the album.

I found myself peering around the stage trying to spot a second guitarist hiding behind bass man Jay Lysaught (Pop Fiction) and drummer Alex Karan (Blo-Pop), but Valenzano (Ellen Rosner, Ripley Caine, The Young Fathers, The Choke Orchestra) is a good enough guitarist to play his own leads without sacrificing a note of his silk-sleek vocals. He easily slips from upper fret Beatlisms to more aggressive fills and solos, dabbling in rockabilly rough and tumble, hard rock grind and even a moment or two of Metallicasms in the set's finale.

The first track from Loomis' full-length CD, Heavy Balloons Are Laughing at Us, opens with a pop riff that sounds like the lead lick from a Third Eye Blind single, then kicks into a solid little piece of hard candy called "It's Too Hard" that was voted the number one track one week on a World Wide Web competition with over 8,000 other entries (on Garageband.com, a web site honorifically chaired by Sir George Martin).

The album's other highlights include the memorable pop number "Waiting for Guns," the rockabilly ride "1,000 Ways to Die" (sadly one of the missed numbers on the set, depriving the Nevins crowd of the chance to see how well they pull off their most challenging song in concert) and the aching acoustic ballad "Nothing Left to Feel." Somehow the band's few forrays into darker material play better on CD than in the Nevins show, where a mid-set dip into heavier material seemed a subpar interruption of aesthetic unity. In context on Heavy Balloons, however, the hard-charger "Cracks" wins points both for being more aggressive than many of the artists to which the band draws comparisons, and for proving the band's stuff can sometimes benefit from more expansive production choices.

Preceding Loomis Saturday night were the Gelflings, whose gritty brand of grrrrrl punk boils things down to the bare minimum of buzzy basics, leaving me wishing I could understand more of their lyrics. The evening was topped off by Chlorine, who describe themselves on their website as "a guitar-driven power trio … inspired by Midwestern power pop, late 70's punk, and indie rock." While that may sound a little bit like Loomis minus the Brit-pop, the trios sound little alike. Chlorine funnels those influences through arena rock bravura (thanks in part to an echo effect left on lead singer Brian Magnusson's mic even in-between songs) surprising in a small club with only 40 lookers-on.
