The Penrose bros will be taking over The Balcony at The Troc this evening, and they have plenty to celebrate! Yes, it’s 4/20, but it’s also broster Tom Murphy’s b-day so I’m guessing that they’ll have things cranked up to 11 to let those big blues rock riffs vibrate through the 2nd floor balcony bar. Well, make sure to wish him a happy birthday and share a plethora of bowls to keep the good vibes rollin’ (and don’t forget the papers). I’m also sure that he wouldn’t mind a shot or five. Cheers!
