“Groupmuse – started in 2012 and run by [Sam] Bodkin, Ezra Weller and Kyle Nichols-Schmolze – matches Groupmuse users looking to host a concert with willing musicians needing a venue to perform. Once a match is set up, other ‘Groupmusers’ are invited to attend, creating an event that’s part house concert, part party, part social platform.” (includes video)
