The Wild Bunch were pioneers of amalgamating a very wide variety of genres. Their shows mixed disparate styles including elements of punk, R&B and reggae. Further, it was their unique focus on slower rhythms and ambient electronic atmospheres that laid the foundations of Bristol sound, which later developed into the popular trip hop genre. They were key members of the Bristol underground scene.
