"Infectious C" is a mesmerizing chromatic groove using a voice leading move on the second string. This progression is actually pretty static in nature, but I thought it was worth exploring. The chords are C7 - Bb/C - Cdim7 - C7, constituting a V - IV/V - Vdim - V progression.
We're in the key of F, but resolving tightly to the V chord (C7). The bass is walking chromatically in pulse with the drums which I really dig. Try using C Mixolydian mode and Cmi pentatonic for some soloing goodness.
