This hymn to Seasick Stick's trusty one-stringed bass is the opening track on the American bluesman's fourth album, Man From Another Time. The record was produced, written and co-engineered by Seasick Steve who performed everything, aside from drums which are credited to his longstanding Swedish sticksman Dan Magnusson.
The song is basically a set of instructions for replicating one of Steve's distinctive home-made instruments, in this case his one-string Diddley-bow (a 2x4 with a string nailed to it). The Diddley-bow, which is played with a slide, is significant to blues music in that many blues guitarists got their start playing it as children.
"Piano Man" was inspired by Billy Joel's time playing at a piano bar in Los Angeles. The "real estate novelist" was a guy who always talked about writing a book, but spent all his spare time in the bar.
