The classic rock instrumentation of electric guitar, electric bass, drums and vocals was set by Buddy Hollie.
Holl
ie? Really?
Holl
y’s bassist, Joe B. Mauldin, used a standup bass for years, and that’s what you hear on the classic recordings. He did eventually move to electric, then Waylon Jennings took over for road gigs, most notoriously that last tour, but that was pretty late in the day, 1959.
Way before that, Gene Vincent’s Blue Caps had taken the similar route, acoustic bass first, then electric(with rhythm and lead guitars), Elvis himself played an electric(for the first time on one of his recordings)for ”Baby I Don’t Care”, 1957, with Bill Black finally converting on “Jailhouse Rock”, same time period, but they already had the two guitars, (acoustic)bass, drums set-up in place, whereas Holly initially was a trio(with the upright)only later adding Nikki Sullivan on second guitar. Carl Perkins as well had a second guitarist in a quartet. Eddie Cochran was already up and running with only an electric bassist before Holly came along.
But before all that, while there may have been sax(a 50’s rock mainstay)or piano, there were these forerunners, with electric bass….
And of course…
