Bruce Katz (born August 19, 1952)[1] is an American musician, playing piano, organ and bass guitar.

He began his professional musical career playing piano and bass guitar with various bands in Baltimore.

From then until the present he has led his own band and simultaneously maintained a sought-after sideman status, recording and touring with many other artists, such as Delbert McClinton, Duke Robillard, Joe Louis Walker, Debbie Davies, David "Fathead" Newman, John Hammond and others.

Katz performed with Allman Brothers founding member Butch Trucks in two different groups --- 'Butch Trucks and the Freight Train Band' and 'Les Brers', a band that contained five members of the Allman Brothers Band and Katz on keyboards, Lamar Williams Jr. on vocals and Pat Bergeson on guitar, in addition to Butch Trucks, Jaimoe, Marc Quiñones, Oteil Burbridge on bass and Jack Pearson on guitar.

Katz also performed with Jaimoe and 'Jaimoe's Jasssz Band', recording and writing on the Renaissance Man CD.

This album featured Ray Hangen on drums and continued to combine original instrumental and vocal music.

It also featured Jaimoe from the Allman Brothers Band on drums on three tracks, most notably a tribute to Butch Trucks called "Freight Train".
