Who's Calling is the 16th solo album by guitarist Harvey Snake Mandel, and his second for Tompkins Square. He is widely considered one of the most innovative guitarists to emerge from Chicago in the 1960s, alongside icons Charlie Musselwhite, Barry Goldberg, Steve Miller, Michael Bloomfield, Paul Butterfield, and Corky Siegel. Along with his peers, Mandel learned in the blues clubs of Chicago's West and South sides, watching, then sharing stages with the masters: Muddy Waters, Howlin' Wolf, and Buddy Guy. Since releasing Cristo Redentor, his 1968 debut solo album, Mandel has worked across the musical map, from blues and jazz to spaced-out psychedelia and whomping funk -- and developed the now familiar two-handed tapping technique along the way. 2016's Snake Pit, Mandel's debut for Tompkins Square, appeared as a comeback after a decade away dealing with serious health problems and recovery. Who's Calling arrives as the 77-year-old Mandel faces renewed health challenges. His trio here includes returning drummer and co-producer Ryan Jewell (Ryley Walker, Laraaji) and bassist Andy Hess (Gov't Mule, Black Crowes). The album's eight originals are offered in Mandel's inimitable genre-bleeding style. The production is raw, immediate and dirty, yet intimate.
