For more than a decade, Hendrix hosted a series of free concerts, open to the public, featuring names to make any music geek's head spin: Lucinda Williams, John Cale, Bill Frisell, Van Dyke Parks, Gillian Welch. That series is no more. But Hendrix certainly hasn't quit booking national acts. In fact, this year, the college might've been Central Arkansas's hippest venue, as it hosted performances from four of indiedoms most revered: Girl Talk, Clipse, Deerhunter and Grace Potter and the Nocturnals. Too bad, at least for non-students, all but Grace Potter required an invite from someone on campus.
