I recently heard a Jack Hart and his Hired Hands tune named ‘Knock out the Lights (and Call the Law)’. I don’t recall ever hearing it before. The recording features a great solo by Jimmy Brant that reminded me of a musical break through I had years ago after learning his solo on Tennessee Ernie’s Rock City Boogie. It was the first time I realized you could solo over chords that the rest of the band wasn’t actually playing, especially if the rhythm section is just bass and drums. For instance the solos in both songs are over the basic three-chord 12 bar blues form. On both solos at the ninth measure, Jimmy plays almost the same lick that’s basically a IIm7 arpeggio. Then over an altered V7 chord in the tenth measure. It’s a useful trick if you’re a wannabe jazzer like myself.
