Jam Cruise 12 continued its journey to a private island in The Bahamas yesterday. The day’s music kicked off with a Pool Deck set from Monophonics, before ALO took the stage for a performance that featured a sit in from Trey Anastasio Band’s Jennifer Hartswick for “Piece of My Heart.” Hartswick recently toured with members of ALO and Kyle Hollingsworth as the Incidental Animals.

The days first big surprise came when George Porter Jr., the Disco Biscuits’ Aron Magner, Brothers Past’s Tom Hamilton, Steve Kimock and John Morgan Kimock joined forces on the solar stage for a fantastic set of Grateful Dead covers. The unscheduled supergroup was created to replace Brock Butler, who was unable to make it on to the boat. That show was then followed by a crowd-pleasing Pool Deck set from Orgone.

Unfortunately, Pork Tornado ended up canceling their set because of Jon Fishman’s absence (the Phish drummer was sick and did not make the boat). However, their slot was filled by the day’s next big surprise—Electron. The supergroup—Disco Biscuits’ Magner and Marc Brownstein, Lotus’ Mike Greenfield and Hamilton—brought a heavy dose of jamtronica to the top of the boat. The music then continued with a Alan Evans-led super jam that featured appearances by Lettuce/Soulive guitarist Eric Krasno, Lettuce/Rustic Overtones saxophonist Ryan Zoidis, Hartswick and many more.

Bootsy Collins & The Funky Unity Band, Thievery Corporation and Mike Dillon Band were the first acts of the day to play concurrent sets. Thievery’s performance featured a number of repeats, including their cover of Sly & The Family Stone’s “Thank You (Fallettinme Be Mice Elf Again), “while Mike Dillon Band invited The Revivalists’ Dave Shaw and Galactic’s Stanton Moore to join them on stage in the Black and White Lounge.

Lotus were next up with a set that saw Mr. Lif sit in for a track from the band’s recent hip-hop album Monks before Hamilton joined the group for “Hammerstrike.” Meanwhile, Karl Denson’s Tiny Universe received some help from Victor Wooten, Nigel Hall, Eric Bloom, Anders Osborne and Will Bernard. Elsewhere, Skerik’s Bandalabra opened up their stage to Mike Dillon, Carly Meyers, 20th Congress/Dap-Kings saxophonist Cochemea Gastelum and some of the Bonerama horns on the other side of the ship.

The collaborations continued throughout the day: Eric Krasno, Billy Iuso, George Porter Jr., Mike Dillon and Maggie Koerner sat in with The Revivialists before Roosevelt Collier helped the New Orleans rockers close out their show with a fun rendition of “Forgot About Dre.” Dumpstaphunk kept the party going with a guest-filled late night set the featured sit ins from Victor Wooten, Cyril Neville, The Shady Horns, Jennifer Hartswick, Billy Iuso, Robert Randolph, George Porter Jr., Skerik and Kofi Burbridge.

The collaborations kept going in the Jam Room, where Lettuce/Break Sceience drummer Adam Deitch was busy leading the charge. The drummer got some help from his parents during the show, which also included appearances by Seattle drummer
Dvonne Lewis, Nigel Hall, Lettuce guitarist Adam “Shmeans” Smirnoff, Lettuce bassist Erick Coomes, Cochemea Gastelum, George Porter Jr., Zach Deputy, Victor Wooten, Dumpstaphunk guitarist Ian Neville, Dumpstaphunk bassist Nick Daniels and many more over the course of almost four hours. The revelry then continued as Brownstein spun an early hours set in the disco.
