No matter how big our neighbor's TV or how good his sound system, we're never going to give up going to shows. There's something about an audience — heightened attention, mutual appreciation, concurrent neural oscillations — whatever it is, it matters. Maybe this is really why people say they wish you were here when they see a sunset. At Music for a Changing Tide you may experience this sensation, joined by an entire audience in an intimate event that combines the shared experience of a listening party with the rugged majesty of Ocean Beach at sunset. In keeping with the theme of this year's Soundwave multimedia biennial, to ponder the elemental nature of water in unexpected ways, Seattle sound artist Nat Evans has composed time-and-space specific music to accompany the receding tide, and inform deep observation. Even if it's foggy and cold as only summer can be, we think that, witnessed as a group, the subtle shifts of sand and light are mindblowing. Participants are asked to download the music ahead of time for either the sunset or twilight tour.
