Tamalpais Research Institute

Tamalpais Research Institute, also known as TRI Studios, is a virtual music venue in San Rafael, California. It is the brainchild of Grateful Dead guitarist Bob Weir, currently of Dead & Company as well as Bob Weir and Wolf Bros. TRI is a state-of-the-art multimedia performance studio, designed for broadcasting live high definition (HD) video and audio streams directly over the internet.

Furthur
On Tuesday, June 7, 2011, Furthur performed live at Tamalpais Research Institute. The event, billed as "Furthur Experiments at TRI", was broadcast in real time over the internet in HD video with stereo sound and was available to those who ordered the pay-per-view event for $19.95. The performance included 13 songs (counting Terrapin Suite as one song), had no break, and lasted about two-and-a-half hours, beginning 6:00PM PDT. The performance was also simulcast for free in New York's Brooklyn Bowl ("BOWLcast"). While the performance was well received by fans, several had trouble viewing the event due to technical difficulties related to server/website load balancing software (subsequently corrected). As a result, TRI Studios rebroadcast the entire concert as a continuous loop stream from June 10, 2011, at 12:00 Noon until June 12, 2011, at 6:00 PM PDT, and made it accessible to those who had originally paid for the event.
