With as much an emphasis on site artistry, interactive experiences and experimentation as the musical entertainment itself, Catalpa is filling what we see as a gap for an event quite beyond the ordinary in New York City.A meeting point for creativity, Catalpa will feature over 40 performers from many musical genres including Blues, Rock, Hip-Hop, Electronic, Reggae and Indie. Art installations of all scales, bespoke event structures and enough unique elements will be present to transform people out of their ordinary setting and into an environment more fantastic.Catalpa will be held on Randalls Island NYC from 1pm to 11pm over July 28th/29th weekend, 2012.
