for me, really great dynamic white 1950s rock sound

discovered while looking into the 1957 album:
"Rock All Night!" [Mercury 20293] (much later reissued by Ace) https://www.45worlds.com/vinyl/album/mg20293
which has rock music from the film produced/directed by Roger Corman https://en.wikipedia.org/wiki/Rock_All_Night

the 1 hour "Rock All Night" film is on YouTube: https://www.youtube.com/watch?v=0unyH7KIqgk
the Blockbusters first appear at 13:13 with "I Wanna Rock Now"
and then "Rock And Roll Guitar" itself is introduced at 16:09
