Santana re-imagined the roles of instruments in a rock group. The prominent Latin percussion section precluded the need for Guitar Rhythm, and Carlos’ melodic guitar acted like a saxophone in a jazz group. This thrust Gregg Rolie and his Hammond into a neo-orchestral position as the main harmonic voice. The entire group hung on his framework. Even though the band bears Carlos’ name, it is nearly impossible to think of their music without hearing Hammond Organ. After moving on from Santana, Gregg drove another group to Mega-Stardom from the console of his Hammond. Journey’s music is loved all over the world, and Gregg’s powerful influence is felt in their music. In recent years, Gregg has been a member of Ringo Starr’s “All-Starr Band”, while also touring with his own group. No matter who Gregg plays with, the integral ax he wields is his trusty B-3.
