But it even took some friends two years to make their first concert. Twenty is certainly marginal. Bob Bossin allows 5 sq ft per person. That doesn't allow for sofas, aisle space, stage or other furniture. We have a 24 x 20 ft building and can seat and feed snacks to 40 plus.
People enjoy the intermission .
Don't make it too short. You will find you are building community, and this is when most products are sold. Announce your next concert. Have a mailing list for signing. Scares hell out of some performers.
