It doesn't get much more hipster than going to a concert that takes places in a third floor walk-up in Brooklyn. Although (being a classical harpist) this isn't normally my scene, I made the hike out to Flatbush the other night because a harpist friend of mine was playing. Liann just recently moved to New York City, and this was her debut performance.
I haven't done too many, but I've always liked playing house concerts. It's a totally different vibe than a concert hall - much more relaxed, and much more personal. The audience is sitting on couches and armchairs and the floor not much more than a few feet away from you, so you can talk and connect with them more easily. This can also be a little bit scary. It's almost as if being on a stage with some distance between you and your audience is a little bit safer, but I like the more intimate feeling of just playing in a living room for some friends.
House concerts are a good place to test out rep before you bring your music to a more public place - Liann played Pierne's Impromptu Caprice and the Pescetti Sonata.
Liann also performed in a trio for harp, bass, and trumpet by Sean Muzzi (the bass player).
