One of the ways that I start some of my clinics is I’ll play the first 15 seconds of Led Zeppelin’s “Rock and Roll” from 1972. Everybody knows John Bonham’s famous drum intro for that song. And then I’ll play Little Richard’s “Keep a Knockin’ (but You Can’t Come In)” from 1956 which literally starts, almost note for note, with the same drum rhythm. Then I put on Louis Jordan’s “Keep A Knockin’ But you Can’t Come In” from 1937 which has a cool little drum lick in it. In 90 seconds I’ve taken the audience from 1972 back to 1937 and shown them a direct lineage of influence and give them kind of an “a-ha!” moment.
