Three of the five songs on the album were covers of songs originally released by soul artists. "Hold On, I'm Comin'" (by Sam & Dave), who recorded at Stax records (with the Stax rhythm section), and "Chain of Fools" (by Aretha Franklin) who recorded that song with the classic Muscle Shoals Rhythm Section at FAME Studios in Muscle Shoals, Alabama.
Two members of the rhythm section on Franklin's recording (Gene Chrisman and Tommy Cogbill) perform on Memphis Underground.[5]
A third song, "New Orleans", was also released by R&B artist (Gary U.S. Bonds), who recorded in Virginia.
So though the only one song was certifiably of Memphis vintage, the conglomeration of young New York jazz musicians with one of the most storied Southern rhythm sections proved to be the catalyst for creating strong, fresh music that sounds like neither Memphis soul nor New York jazz. This unique sound appealed to a large audience.
Reception
The record is one of the best-selling Jazz albums of all time. Rolling Stone said "Memphis Underground is a piece of musical alchemy, a marvelously intricate combination of the "Memphis sound" and jazz lyricism".[6]
Memphis Underground was a favorite album of writer Hunter S. Thompson, who mentions it positively in several chapters of his book Fear and Loathing on the Campaign Trail. In the article The Battle of Aspen, Thompson states that his "Freak Power" campaign used Mann's recording of "Battle Hymn of the Republic" as the background music for their commercials.
Another writer, the British author Stewart Home, as a tribute to this Mann album, titled his 2007 novel (some call it an antinovel) Memphis Underground. In the novel, Home makes multiple references to soul, northern soul and jazz soul music.
