Here's a personal description from the artist:

"I'm KJ Sawka and I'm excited to introduce the 'Mad Beatz' drum n' bass, dub step and breakbeat collection exclusively for Ableton Live, as a special holiday gift. I'm proud to be part of the world changing Ableton team!

'Mad Beatz' is mainly drum and beat-oriented stemming from a live acoustic drumming session recorded at the Art Institute in Seattle, Wa USA. There are also plenty of electronic drum loops, percussion, basslines and keyboard riffs."
