1978 US Columbia House club pressing. "Briefcase Full of Blues" is a live album by the Blues Brothers, released on November 28, 1978, by Atlantic Records. The album captures the energetic performance of Dan Aykroyd and John Belushi's comedic musical personas, Elwood and "Joliet" Jake Blues, during a live show at the Universal Amphitheatre in Los Angeles on September 9, 1978. Known for its authentic tribute to classic blues and soul music, the album features covers of well-known hits such as "Soul Man," "Rubber Biscuit," and "Hey Bartender." The dynamic interplay between Aykroyd's harmonica and Belushi's vocals, backed by an accomplished band that includes members like Steve Cropper and Donald "Duck" Dunn, contributes to the album's raw and spirited sound.

"Briefcase Full of Blues" was both a commercial success and a cultural phenomenon, reaching number one on the Billboard 200 chart and earning a double platinum certification. The album's release helped to solidify the Blues Brothers as a legitimate musical act, beyond their origins as a comedic sketch on "Saturday Night Live." The infectious energy of the live performance and the duo's genuine love for the blues genre resonated with audiences, bridging the gap between comedy and music. This album not only set the stage for the Blues Brothers' subsequent film and tours but also played a role in the late 1970s revival of interest in traditional blues and soul music.
