The first steps of his musical journey began in Northern California in the boiling cauldron of creativity that was the San Francisco psychedelic scene. Jimmy, at the age of 17, began jamming with many of the musical legends of the time and by the early 1970s had established himself as a major force in the Blues, Soul and R&B genres.
In the 1970’s and early 80’s Jimmy performed and recorded with many artists. Jimmy played with Sly & The Family Stone (1974-75) and for four years toured nationally and internationally with Edwin Starr & Starrchild (1978-1982). One of the many highlights of Jimmy’s early career with Edwin, while opening for Marvin Gaye was selling out Royal Albert Hall for two consecutive shows . In 1981 Jimmy performed with Kim Carnes for the rock video Draw of the Cards, one of the first videos ever broadcast on MTV.
Jimmy toured Japan with Hiroshi Takabo as a piano/bass duet performing jazz and blues with an international flavor. The tour traveled throughout Japan and was notable for selling out every single performance.
Jimmy returned to the States in 1983 and formed the band Killing Time. Killing Time headlined the inaugural “Earth Day Festival” at U.C.Davis. While playing with Killing Time, Jimmy was asked by Michael Shrieve and Pete and Coke Escovedo of Santana to perform a special engagement with Lydia Pense and Cold Blood. Jimmy and Coke hit it off musically, and beginning in 1984 they hit the studio for a number of recording sessions featuring Coke’s original music, but the album was never completed due to Coke’s untimely passing in 1986.
In 1984 Jimmy joined forces with Christian and Soul music great Jon Gibson. Jimmy toured and recorded with Jon for four years, and during that time recorded the albums “On The Run” featuring Joe Satriani and “Change of Heart” featuring M.C.Hammer. Both of these records produced #1 hits on the CCM Charts. It was during a performance on the support tour for “Change of Heart” that M.C. Hammer yelled out to the audience ”I need some help from my ace, Jimmy Mack on bass!”
From that day on, this became part of the tour, and Jimmy has been known as “Jimmy Mack” ever since.
After touring with the band 50/50 (The Jon Gibson Band) in late1988, Jimmy realized he needed to take a break. Jimmy spent the following two years meditating and writing music, while routinely performing with such respected musicians as Francine Reed (Lyle Lovett) and Motown Hall of Fame drummer Jerome Teasley (Junior Walker and the All Stars).
In 1991-92 Jimmy recorded the album “Walk The Line’ with Mary Wilson of The Supremes, only the second solo album that Ms. Wilson recorded in the previous 30 years. “Walk The Line” was released in August 1992 and included the hit single “One Night With You”.
Jimmy began recording and touring nationally and internationally with Richie Havens in 1993 and performed with Richie through 1996. One of the highlights of Jimmy’s time with Richie was performing at the original site of Woodstock for the Bethel 25th Anniversary Woodstock Concert. In addition to Richie and Jimmy, other performers included Country Joe McDonald, Melanie, John Sebastian, Mountain, Blood, Sweat and Tears, Canned Heat, Iron Butterfly and Sha Na Na, as well as Fleetwood Mac, Judy Collins, the Chambers Brothers, Tom Paxton and Leon Russell. Jimmy appeared with Richie on ABC's “Live in Concert” broadcast and recorded the “Cuts To The Chase” album released in 1994 by Rhino records.
In 1996 Jimmy formed the rock band Thomas Thomas and toured regionally until 2000 when Jimmy was asked to create and arrange the score for a television pilot in pre-production. The networks did not pick up the show, but Jimmy continued to work in broadcast media creating and performing soundtracks and voice overs for commercials. During that time, Jimmy also performed regularly with Arizona Blues hall of Fame Artists Hank Tomlin and Tommy Dukes. Jimmy himself, was inducted into The Arizona Blues Hall Of Fame in 2004 for making a lasting and substantial contribution to the blues culture in the State of Arizona. At his induction, Jimmy was described as “a living blues legend”.
In 2003-04 Jimmy recorded the album “One Mans Trash” with Jeff Bell which included the hit single “I’m a Dog” and in 2005 toured nationally in support of the album.
From 2005 to 2008 Jimmy again took a hiatus from touring and performing, and except for an occasional guest appearance for his friends in the industry, focused his energies on songwriting and arranging his first his solo album.
