Everything, including the music was made exclusively in After Effects with no other programs or plug-ins.
The music was made using the audio effects, such as tone or modulation and key framed to create the drums and melody - challenging since After Effects definitely isn't made for music making!
I've made the project file (CS4) for the music available here:
