Jazz guitar doesn't mean what it used to. With the improv scene lacking any dominant genre (bebop, funk-jazz, fusion), musicians can just play what they feel, and that's an advantage. On his new Coldwater, for instance, local guy Robert Jacobson gives you a sniff of Ornette, Steely Dan, bop and blues, but only a sniff because he's got a lot of ideas, and he wants them all to sound like him. Which they do. The common factors include and edgy electric-guitar tone from Jacobson, slightly sprung rhythms, and layered arrangements that allot each instrument it's own distinct space, Wayne Peet's organ often acting as a soulful foundation.
