There’s going to be a certain groove to this week, prior to the festivities of next. When a couple of Miles Davis collaborators, jazz guitarist John McLaughlin and foremost fusion drummer Billy Cobham got together with keyboard pioneer Jan Hammer, they created something quite mind-blowing. ‘You Know, You Know’ features on jazz-rock album The Inner Mounting Flame. The workout was notably sampled by Massive Attack (‘One Love’) and Mos Def (‘Kalifornia’). Billy Cobham was a drumming machine before such things existed.
