In 1993, Todd Rundgren released No World Order, an interactive CD that allowed listeners to alter the mix and sequence of the music.
That forward-thinking endeavor now seems quaint compared to Rundgren's wholly electronic new album, State, and the laptop-driven live show that the Upper Darby native brought Saturday to the Trocadero.
Rundgren, 64, has chased various muses since founding psychedelic rock band the Nazz in the late '60s. There has been soft rock, progressive rock, classic pop, hard rock, soul, and now this electronic sound that finds Rundgren seemingly under the influence of Skrillex and Frank Ocean. It's more than an old head hitching his wagon to what's trendy. It's one of pop's great enigmas exercising the freedom he has earned to follow wherever these muses lead.
