An important element of the fusion style during the 1980s was Latin-based music. Pianist Chick Corea has continued to incorporate Latin influences of Brazillian drummer and percussionist Airto Moreira in the Classic Return to Forever band of the early 1970s. The world of Alex Acuna with Weather Report in the mid-1970s was and early example of Latin-influenced drumming in a mature fusion context. This playing required the drummer to approach the instrument differently; intricate sticking patterns were often distributed between the limbs while the bass drum and/or hi-hat played an ostinato pattern, an unusual but infectious sound that created a great deal of excitement. Drummers such as Steve Gadd and Vinnie are important exponents of these influences.
