M/A/R/R/S was a one-shot collaboration between groups A.R. Kane and Colourbox. Together, they released their biggest, and only, single in 1987, "Pump Up The Volume". This dance club favorite peaked at #13 on the Billboard Hot 100, #15 on the Cash Box Top 100, #8 on the Billboard Soul/R&B chart, and made it all the way to #1 on both the Billboard Dance Singles and UK Singles charts. This is a rare version of the song, and definitely deserves a listen.
