Frankie Beverly’s voice mixed with Maze’s laid-back, bass driven musical arrangements differ a lot from other soul acts. Their signature sound is especially vivid on the LP classic Live in New Orleans.

14 Apr Sharon Jones And The Dap-Kings

Sharon Jones & the Dap-Kings are a funk/soul band signed to Daptone Records. They are widely thought to be spearheads of a revivalist movement that aims to capture the essence of funk/soul music as it was at its height in the mid-1960s to mid-1970s. Part of the way this is achieved is to shun modern digital recording methods in favour of using traditional analogue recording equipment. The type of instruments used by the band may also be considered limited to those that would have been available up until the mid seventies.

25 Apr Larry Graham

As a kid, Larry tried piano, clarinet, saxophone, drums, and guitar before finding his true calling. His multi-instrumental background and open mind ultimately led him to create an entirely original electric bass style. Some call it slap and pop—Larry calls it “thumpin’ and pluckin’”—and it’s arguably the single most innovative and influential technique in the instrument’s history. Even players who consciously steer clear of its now-ubiquitous presence need to at least have a handle on the technique just to get through a typical wedding set. Larry Graham’s funky creation is a lasting one.
