Beloved Grateful Dead drummer sat in with Leftover Salmon at The Fillmore last weekend, promising fans that he had something in store for Inauguration Day. The news began to develop as Streamstock was announced, an online, stream-only event that would air simultaneously with the Inauguration. Kreutzmann was announced as a headliner for Streamstock, with his video submission set to stream at the same time as the Inauguration itself.

Kreutzmann chose to perform with a brand new band for the occasion, taking footage from an early January jam session with a group dubbed the Rooster Conspiracy. After teasing the members on social media for a day or two, Kreutzmann revealed that Eric Krasno, Reed Mathis, and Todd Stoops were the three men involved with the project.

Behold the video of the quartet’s debut jam session from Kauai, HI, a free flowing improvisational masterpiece with all four veterans staking their claim. You can read more about the inspiration for the project on Kreutzmann’s website, and watch the two-part video below.
