Imagine all the people—carrying on the John Lennon legacy. Love is the Answer: The Concert for John Lennon celebrates and salutes the man who popularized the notions of peace and love through his music. The Plastic Fauxno Band presents a two-and-a-half-hour concert that stands to answer the question, what might Lennon have played if he were still alive today? The concert will span Lennon’s entire solo career, from “Imagine” and “Power to the People” to “Starting Over.” The legacy continues on Saturday, Oct. 1, at Spreckels Performing Arts Center. 5409 Snyder Lane, Rohnert Park. 8pm. $26-$28. 707.588.3400.
