Glasvegas was just your average rough-edged art punk band that takes its cues as much from Elvis and Dion and the Belmonts as they do from rockabilly and the shoegaze style that their fellow countrymen, the Jesus and Mary Chain, made popular. Then British record mogul Alan McGee spotted them in the same Glasgow pub where he first laid ears on Oasis. Next thing they knew, he declared them the greatest Scottish band in the last 20 years and there was a record deal. Now they’re doing a loop in the States in support of their eponymous full-length album debut. If the idea of a tuneful doo-wop band on a wee noise pop bender piques your curiosity, stop by Great Scott (1222 Comm Ave, Allston, 617.566.9014) tonight. Doors open at 8 p.m.; get tickets ($12) at www.greatscottboston.com.
