House concerts are musical performances generally held in private homes and hosted by fans, friends, or relatives of the performing musician(s). Audiences are usually 25 to 35 people, but can sometimes be as large as 60 or more, and a donation of $15 to $25 is generally requested, but not required. Oftentimes, there is a potluck dinner involved, but wine and cheese events are most common, with guests encouraged to bring a drink to share. Hosts will even sometimes put performers up for a night.
