Ubiquity gathered three of the most sampled drummers in hip-hop music and commissioned them to replay their most sampled loops and some new originals with the producer in mind. The first two volumes are all Purdie!! The sound quality and presentation are unrivaled. I've got a number of "live drum break beat" records in my collection and the Ubiquity Master Drummer series are packed with the cleanest and the most classic breaks a producer could ever hope to come across.
