I came to this by way of the superb podcast of the same name, which I highly recommend. In truth, the podcast has the added advantage of including snippets of the songs he's analysing, but the book format allows the reader to flip back more easily when necessary. Hickey doesn't begin with, say, That's All Right, Mama, or even Rocket 88, but way back in the swing era, with the Benny Goodman Sextet's 1939 recording of "Flying Home". As Hickey says, you have to begin somewhere, and this song, containing an innovative guitar solo by Charlie Christian and, (in a slightly later version) a honking sax solo by Illinois Jaquet is as good a place as any.
The story then continues with Big Joe Turner's "Roll 'Em Pete" This song is crucial to the development of rock and roll, not, as Hickey is at pains to make clear, because it is the first instance of the backbeat, ("The first of anything is messy", says Hickey) but more for the combination of boogie-woogie piano, backbeat, and bluesy "floating" lyrics. All the elements of rock and roll are there.
We then get chapters on Bob Wills and the Texas Playboys, Louis Jordan, Sister Rosetta Tharpe and many more, including Fats Domino, Les Paul, Johnny Otis, Johnny Ray, Hank Williams and up to the performers who first come to mind when I think of fifties rock and roll - Bill Haley, Chuck Berry, Bo Diddley, Little Richard and Elvis, ending the first volume with Mickey and Sylvia's "Love Is Strange". Erudite yet readable, this is a must-read for any music fan.
