1) Send email and Facebook invites to friends. Let them know you'll be hosting a singer/songwriter "House Concert" in your home. Include any details you know about the artist as well as the date/time of the event. Suggest a donation of $15-$20 per person for everyone who attends the show.
2) Invite only as many as your room/area will hold comfortably. Folding chairs and throw pillows are all acceptable. Make the atmosphere a relaxed one.
3) Create a clear space to be utilized as the “stage”, and ample space for the audience as well. Even though it's an informal setting, try to give the performer the most visible spot in the room or area you are using for the show.
4) Be sure to let your guests know there will be two 'sets' during the evening. The first typically starting around 8:00pm (exact set times should always be worked out in advance between performer and host). The break between sets is part of the real charm of the House Concert. This gives the guests a chance to meet and chat with the artist.
5) Provide a small table that is easily accessible to your guests, so that the artist may display 'merch' items such as CD's, DVD's, and even books. Many artists rely on merch sales as a part of their regular income. When your guests purchase a CD, they can enjoy the music whenever they like, AND support the artist directly.
6) Personalize the event. Make the night feel less formal and more personal. Offer your guests wine and beer, like you would at any gathering in your home. It's certainly okay to have a full-bar available, just try to remember not to turn on the blender to mix those margaritas during the performance.
7) Ask your guests to 'silence' their cell phones during the performance...and enjoy YOUR show.
