Sitting on a stool – but looking as if he’d be happier hopping around – Steve Poltz accompanied himself on guitar and played homespun acoustic rock songs from his week-old solo album, “One Left Shoe.” He padded his two-hour set – which is brief by Poltz standards – covering cuts by TLC’s “Waterfalls,” Prince’s “Little Red Corvette” and Jewel’s “You Were Meant for Me.” Poltz, who still is in the Rugburns, included some of his group’s material as well.

There is such strength and purity to Luka Bloom’s music that a band could only diminish the conviction of his songs. Standing alone on a barren stage at the Park West Friday night with just his electro-acoustic guitar for accompaniment, Bloom gave a sly but powerful performance that ended all too soon.

“Yeah, I guess my next step is making a disgusting sexist video for MTV,” Luka Bloom said, laughing. “But my treatment would have to be very different. For an Irish rap song, we’d have to get green babes. No, I go for the pretty soft videos, which I hope aren’t too schmaltzy. But as long as it doesn’t get mistaken for one of Michael Bolton’s, I’m fine.”
