Great quality 'twangy rockabilly surf' music from Industrial Strength. You get 6 kits with drums, bass and guitars. No other instruments. Guitars are super authentic and are the driving force behind the sound. 85 - 115 bpm which is right in the pocket. You also get a small folder of some percussion loops as well as a folder of music and drum one-shots for an added bonus. If you want that 50/60's summer LA surf vibe with some extra "umph"... this is an excellent set.
