My most memorable moment was when Lake Street Dive first came to OLS. There were about 40 people in the audience. Their musicianship was excellent: Bridget Kearney’s complex bass lines, Mike Olsen’s soulful trumpet and spare electric guitar and Mike Calabrese on the drums. But when Rachel Price began to sing with her deep, jazz voice, she had the room in her hand. Lake Street Dive played twice again at OLS before their next step, which was selling out the State Theater.
