Underground Resistance are reissuing for the first time since vinyl cutting master Ron Murphy’s death, who pioneered the art of weird vinyl in dance music.
- Multiple bands: Records cut with separate rings, where the bands on the vinyl appear as separate tracks, e.g. Moby Grape Wow/Grape Jam
- Locked grooves: Where the record ends with a closed loop with a sound recorded into it, e.g. Underground Resistance Discovers The Rings Of Saturn
- Lead-in grooves Where the usually silent lead-in groove has sound recorded into it, e.g. The Dead Kennedys Plastic Surgery Disasters
- Parallel/Concentric grooves: Where, depending on where the needle is dropped, a different track will play, e.g. DJ Bone Riding The Thin Line
- Reverse: Where recordings play from the centre of the disc outwards, e.g. Inner City Ahnonghay
- Stereophonic format: Each side of the record consisted of two tracks of the song, one containing the left channel, one the right. A special adapter would need to be bought to play this.
- Quadrophonic format: Recording with four channels of audio instead of two.
- Vibration-resistant discs: Designed for use in cars, with a slower play speed and high pressure stylus.
