Before they kick off 2012 in style by doing a recording session with Bill Moriarty (Dr. Dog, Man Man, Hoots and Hellmouth, Drink Up Buttercup, etc.), Penrose are giving 2011 one last hurrah with a pre-New Years Eve bash at Tritone tonight. 2011 proved to be a fine year for the Brothers Murphy that saw them win the Fans’ Choice portion of our Best of Philly Emerging Aritsts Poll, featured on CMJ’s website, launch the No Excuses Summer Series, and more. And they’ll be ending it on a good note by debuting some new songs this evening. Rockabilly countrified blues masters Levee Drivers are another band that will be hitting the studio with new material in 2012 so you should be treated to some new songs to kick back plenty of specials to help you get rowdy. Add in the soulful blues rock of John the Conqueror and the melodic alt folk of The Lawsuits, and you have a solid lineup to get you warmed up for tomorrow night’s festivities. Tritone, 1508 South St., 9pm, $8, 21+ – Bill McThrill
