Barenaked Ladies in concert with Toad the Wet Sprocket at the Thomas Wolfe Auditorium. After more than three decades as the lead singer and guitarist for Barenaked Ladies, Ed Robertson has a routine when it comes time to start writing songs for a new album. “I tend to get ideas while I’m driving up to my lake house,” he says. “I record voice memos along the way, and then I listen back and try to make sense of them and mix and match the various ideas I’ve come up with. On a typical drive, I’m happy if I get six or seven — eight ideas would be a good drive.
