The cafeteria at Folsom no longer holds that specific audience. The guards on the catwalks have been replaced by others. Glen Sherley is dead. Bob Johnston is dead. Luther Perkins died months after the recording. Cash is dead. What remains is the tape, converted to digital files, available on streaming platforms accessible from anywhere in the world. The recording captures a morning in California in January 1968 and makes it available to anyone with a device and a connection.
That is what recordings do. It is what this one does better than most.
## Cash at Sun Records: What He Left and Why
The move from Sun Records to Columbia in 1958 is a transition that most Cash biographies handle briefly, noting the larger label, the broader distribution, and the creative limitations Cash felt under Sam Phillips. But the specifics are worth examining, because the decade at Columbia that preceded the Folsom album was shaped substantially by what Cash was escaping and what he was moving toward.
Sam Phillips was a visionary producer whose specific gifts were suited to a particular kind of music-making. He had invented, or at minimum been the crucial midwife of, a sound — rockabilly, the collision of hillbilly country with rhythm and blues — that was transforming American popular music in the mid-1950s. He had an extraordinary ear for raw talent and an ability to capture performances that sounded alive in a way that more polished recordings did not. His studios on Union Avenue in Memphis became one of the most consequential recording spaces in American music history.
