As a teenager in mid-1960s Duluth, the bands guitarist Bob Flatt played in often had to create their own venues and showcases. Sometimes renting out places like the YMCA or Shrine Auditorium, they’d handle everything from selling tickets to concessions to making fliers, not to mention playing long sets of blues-orientated rock music. Fast forward 50 years and his artistic spirit lives on in Group Too. Joined by Carol Flatt on bass and shared vocals, they usually perform as a folk duo. For Homegrown, however, they plan on delivering a heavier blues set with guitarist Israel Malachi and drummer Todd Gremmels.
