Big Daddy Love and Paper Thick Walls performed at the Northwestern University 2012 PhilFest held in mid-May in Evanston, Illinois.
The annual bluegrass concert, co-sponsored by A&O Productions and Students for Ecological and Environmental Development (SEED), is held in memory of Phil Semmer, a SEED member who passed away while studying abroad.
The event raises money for the Rocky Mountain Institute, and organization that researches more effective use of resources and that Semmer aspired to join after graduation.
