Join us as three Envelop Board Members take the stage to celebrate 10 years of Envelop. Co-founder and Executive Director Christopher Willits, a groundbreaking ambient composer, producer, and guitarist, opens the evening. Mark Slee, lead developer of Envelop's spatial audio software (E4L) and large-scale light artist, follows with his signature intricate grooves. The night closes with an unrepeatable B2B between Mark Slee and The Ride, the DJ alias of co-founder and Envelop Board Chair, Roddy Lindsay, known for deep, hypnotic grooves rooted in two decades of collecting classic disco and house records.
A decade ago, Envelop was founded on a belief that our world needed spaces where people could listen and feel together, not just for fun and entertainment, but for connection, inspiration and empathy. Ten years later, that belief has grown into a global community, free open-source tools used by artists everywhere, a permanent listening space in San Francisco and Envelop Pop-up activations beyond, and thousands of events and hours of shared listening experiences.
Open bar. Limited tickets. Standing room only. Plus, exclusive donor opportunities are available only at the event.
