Many musicians in town for New Year’s Eve shows of their own participated in a late night jam session at San Francisco’s Boom Boom Room last night. ALO guitarist Dan Lebowitz anchored the guest-heavy performance, offering a set that stretched through with midnight along with the evening’s house band: ALO bassist Steve Adams (bass), Fletcher Nielsen (keys) and Inkx Herman (drums) as well as special guest Sean Leahy (guitar). The musicians offered a range of covers during their set, including Grizzly Bear’s “Two Weeks,” a boogaloo reworking of The Beatles’ “Run for Your Life” and Taj Mahal’s “Further on Down the Road.” As their midnight countdown began, the group invited out the members Adams’ other band Big Light for a celebratory cover of Talking Heads’ “Burning Down the House.”

After Lebo’s first segement, Big Light played a late night set that featured covers of Bruce Springsteen’s “Thunder Road” and The Rolling Stones’ “The Last Time.” Lebo then returned with his band to play a few additional tunes. The set gradually blossomed into a late night SF Gramble featuring many area musicians and guest performers. First, Tedeschi Trucks Band trumpeter Maurice Brown and New Mastersounds keyboardist Joe Tatton—both of whom were in town for a set at San Francisco’s Warfield—appeared on a cover of The Meters’ “Cabbage Alley.” The New Mastersounds rhythm section of Simon Allen and Pete Shand then took the stage with Leahy, Brown and organist Will Blades for a take on Grant Green’s “Jan Jan.”

Soon after, the evening’s theme shifted from funk to bluesy rock when Slip guitarist Brad Barr as well as Big Light guitarist Fred Torphy and Jeremy Korpas joined Lebo and his band for covers of JJ Cale’s “Cocaine” and Rolling Stones’ “Jumpin Jack Flash.” Lebo’s band also brought out Barr, Brown and others for a version of War’s “Cisco Kid” and invited organist Robert Walter onstage for a take on Jimmy Smith’s “Root Down.”

The night came to a close after 5 AM with Lebo and his band back onstage for Led Zeppelin’s “D’yer Maker” and Bob Dylan’s “Tonight I’ll Be Staying Here with You.” The evening’s VIP endurance award certainly went to Adams, who played bass throughout almost the entire marathon performance.
