Versatile Tweedy Successfully Moves Beyond Uncle Tupelo

As a co-founder of the band Uncle Tupelo, Jeff Tweedy was a key architect of the alternative-country movement, but as the frontman for Wilco, he’s long since left that genre’s restrictions behind. On the quintet’s latest album, “Summer Teeth,” Tweedy imposes any pop style he sees fit on his band. That made for an intriguing musical survey at Wilco’s performance at the House of Blues on Monday.

In his mid 30s, Tweedy is a rock wonk who isn’t afraid to filch at will from all the records he loves, but he’s a canny enough songwriter to make it all work. Just as he used the most obvious country tropes as signposts for his early work, he now constructs baroque guitar rock from the melodic fragments of material from the ‘70s and ‘80s. At the House of Blues, Tweedy and company convincingly morphed from one musical pose to the next--the boozy brio of “Exile on Main Street” Stones, Rockpile’s giddy pub rock, the ornately arranged pop of the Raspberries.

Through it all, Tweedy’s nicotine-stained voice conveyed the bittersweet sentiments of a man who’s been exiled from love for too long. So complete has been Wilco’s transformation that the band’s few attempts at straight-up country sounded strangely inauthentic--the last refuge of artists who aren’t quite yet ready to shed their roots.
