The history of Jamaican Dub music is rich and fascinating. Dub grew out of reggae in the 1960s, and evolved well beyond its popular parent. It was a studio craft where producers created instrumental remixes of reggae tracks by removing the vocals, adding echo, reverb and delay, and dubbing in new ambient sounds. Essentially, dub was an early form of popular electronic music.
If you think all this had something to do with cannabis, you'd be understating the case. In a 1982 essay, LUKE EHRLICH said: "With dub, Jamaican music spaced out completely. If reggae is Africa in the New World, then dub must be Africa on the moon; it's the psychedelic music I expected to hear in the 1960s...and didn't. The bass and drums conjure up a dark, vast musical portrait of outer space, with sounds suspended like glowing planets or the fragments of instruments careening by, leaving trails like comets and meteors."
Dub was a natural link to later electronic genres like techno, ambient, trip hop and electronic dance music.
