Supersonic Blues Machine

Supersonic Blues Machine is a California-based blues rock collective founded in 2012 by producer/bassist Fabrizio Grossi, drummer Kenny Aronoff, and guitarist Lance Lopez (later succeeded by Kris Barras). The project is defined by its 'supergroup' architecture, serving as a hub for elite musicians to collaborate.

Their sound identity is rooted in American roots music, specifically the intersection of Texas blues grit and Los Angeles production clarity. Grossi's background as a producer for icons like Steve Vai and Alice Cooper informs the band's high-fidelity, layered approach to the blues. The band's career arc is marked by significant Billboard Blues chart success and a reputation for high-profile features, including Billy Gibbons, Eric Gales, and Walter Trout. Critically, they are viewed as torchbearers for a modernized version of 'rock 'n' soul,' moving the genre away from purist constraints toward a more inclusive, alternative-leaning sound. They occupy a unique cultural position as a 'musician's band,' frequently cited by peers for their technical proficiency and the 'heavy pocket' drumming of Aronoff.
