In most jazz, rock, blues and pop genres, the bass line outlines the harmony of the music being performed, while simultaneously indicating the rhythmic pulse.  Wikipedia 2007
Some of my favorite all time rythym sections, Blues, Rock and Jazz.
Bass and Drums 
James Jamerson and Benny Benjamin Motown
Bern Calvert  and Bobby Elliot The Hollies
John Taylor and Rodger Taylor Duran Duran
Bernard Edwards and Tony Thompson Chic
Larry Graham and Gregg Errico Sly & the Family Stone
Rocco Prestia and David Garibaldi Tower of Power
Charles Mingus and Chico Hamilton late 40's and 50's Jazz
Paul McCartney and Ringo Starr The Beatles
Four songs for demo purposes. I removed the bass tracks from the original songs as best i could and inserted my own bass playing. Done on the fly. I'm sure I'll be sued by some of the bands for altering their music. Oh well
Listen to with good speakers or headphones and crank it up!
Jonny Lang, CoCo Montoya and John Lennon.
Thanks for listning.
