This is an amazing set of build-ups & breakdowns. If you don't own these separately already - this is your chance to get everything in one mega pack. You get 2 main folders - buildups and breakdowns. Within these, you have subfolders of everything you need to create huge drama in any track. The loops range from 2 bars to 4 bars and are broken down into a great variety of styles like clap fills, combi fills, cymbal fills, kick & snare fills, melody fills, reverses, sweeps, etc.
