Probably the best-known soul guitarist in the world, Cropper came to prominence in the early '60s, first with the Mar-Keys ("Last Night"), then as a founding member of Booker T. & the MG's. A major figure in the Southern soul movement of the '60s, Cropper made his mark not only as a player and arranger (most notably on classic sides by Otis Redding, Sam & Dave, and Wilson Pickett) but as a songwriter as well, co-writing the classic"In the Midnight Hour." After the breakup of the MG's, Cropper spent most of the '70s producing Jeff Beck and Mitch Ryder, among others. In the '80s, he rode the classic Stax sound (which he helped shape) back to popularity with a new audience when actors John Belushi and Dan Aykroyd tapped him for service in the Blues Brothers, a Saturday Night Live skit that stretched into several albums and a movie. Cropper remained in demand as a session man, producer and collaborator into the new century, although very little appeared under his actual name as a recording artist. That changed with the release of the affirming Nudge It Up a Notch, a project recorded with former Rascals frontman Felix Cavaliere and tracked at Jon Tiven's Hormone Studio in Nashville, on the revitalized Stax Records imprint in 2008.
