Satisfy your appetite for music today with Brown Bag It, a lunchtime concert series at the Tulsa Performing Arts Center that's free, casual and open to the public. Tulsa's own Janet Rutland and guitarist Randy Wimer perform vintage jazz and pop in the intimate setting of the PAC's Kathleen P. Westby Pavilion. All are invited to bring a lunch to enjoy during these 40-minute noontime shows.
