Six years later, Wallinger is finished with rehab and back on the road for his first tour in nearly a decade. The one-man band's performances have been unself-conscious; his hopeful, bluesy jangle has warmed up a largely tuneful set -- one inspired by everything from the psychedelic Beatles and midtempo Matthew Sweet to Dylan and the late Arthur Lee of Love. Wallinger's celebratory zeal has stunned audiences at South by Southwest and Bonnaroo, and his savvy songwriting and rapier wit have certainly been missed. In rare form despite the long layoff, Wallinger is playing a handful of dates, offering this brief glimpse of a true pop craftsman.
