The deep rhythmic bass of reggae, combined with the tendency of ganja to enhance ones' appreciation of tonal resonance and to distort ones' perception of time, when mixed together in primitive recording studios, begat dub. It was the custom within the Jamaican music industry to fill out the flip-sides of 45rpm singles with instrumental versions of the song featured on the A side. Under the creative influence of sacramental herb, record producers began twiddling their knobs idiosyncratically, dropping out the treble and pumping up the bass, cutting up the vocal track and adding masses of reverb to haunting phrases that echo through the mix. No other music sounds more like the way it feels to be stoned.
