The scene can arguably be traced back to the o.g. wave of 1960s psychedelia. The jam band circuit, as it exists today, fermented in the twin wake of North America's obsession with festivals, as sparked by Lollapalooza, and Phish's evangelical, Black Flag-like touring.
Williams is one of the genre's stalwart champions, his greatest contribution being the eclectic, hydraheaded nature of his output as engendered by bend-over-backwards versatility. He rose to fame for using gear to forge a singular path as the world's first One Man Jam Band. And he's held the Bonnaroo demographic's attention ever since with records covering everything from bluegrass to R&B, and sessions with some of the biggest Deadhead improvisers around.
In anticipation of Williams' upcoming concert at Revolution, we spoke to the axeman about the secret life of jam bands.
