Sri Naidu (tenor) Sri asked for an audition with DeltaCappella after hearing DeltaCappella open for grammy-winning Take 6 on stage at the Orpheum Theater in Memphis. Sri had sung a cappella in college, with the Men's Octet at Berkeley, before going on to become a prominent Ear Nose Throat doctor in Memphis. And like Jay, he longed to relive his collegiate a cappella experience.
