There's a universe of fantastic rhythm guitar in R&R/Rock and R&B
But some good old-school examples are:
- John Lennon/ early Beatles ( I Saw Her Standing There, All My Lovin', I Wanna Hold Your Hand) and Later, Revolution, Get Bsck
- The guitars in Motowm and Stax hits
- The Stones
- Bob Weir in the Grateful Dead
* all early dinosaur music but timeless to me- I love it!
