We reviewed the Pentax Waterproof camera (The W20) at this years Austin City Limits Festival– declaring it Party Proof. While we were there we used our press credentials to creep around back stage (yes, we were stalking Ben Kweller) when we got this funny picture of a fairly well known rock star wearing bright pink boots. If you know who this is, drop us a note with your answer, we’ll pick names out of a hat next week and announce the winner. Send us an email, don’t bother leaving it as a comment, we won’t approve it– we don’t want to to spoil the guessing fun for everyone else. Full size picture of the mystery rock star after the jump!
