The Blues Brothers knew what they were doing when they recruited ace blues guitarist Matt "Guitar" Murphy in 1978 for their debut album, "Briefcase Full of Blues". Murphy, whose career started all the way back in the 40's & 50's, had played with artists such as Etta James, Muddy Waters, and, in this clip, Memphis Slim.
It would've been too easy to pull another clip from the "Blues Brothers" movie from 1980, where, in the storyline, Murphy and soul legend Aretha Franklin played husband & wife and ran a diner. That clip will come at a later time. Murphy passed away over the weekend at 88.
Rest in peace.
