... When and why did this whole obsession come about (Dub)?
Dub is a culture and music genre ...
Dub (which literally means "to double") primarily refers to the instrumental version of a song, based on the rhythm section of the band. One of the main characteristics of the dub style is the work done by the sound engineer, which includes adding effects such as echoes and reverbs.
Dub was first linked closely to reggae, and evolved between Jamaica and England thanks to artists such as King Tubby, Lee Perry or Mad professor.
When techno exploded in the nineties, the British dub movement really took off, including artists like Zion Train, Alpha and Omega, Iration Steppas, The Disciples, and Adrian Sherwood's famous label, On-U Sound.
At the dawning of the new millenium, dub evolved by breaking off with reggae and rasta culture to become a musical genre in its own right. Being a kind of musical Eldorado (dub allows sound experimentation), musicians from different horizons such as rock, techno, or hip hop, showed great interest in the possibilities that dub had to offer.
Inspired by techno, jungle, or hip hop, electrodub emerged notably in Germany, Italy, Austria (Sofa Surfers), and France (Ezekiel, Dub Wiser, Brain Damage, Kaly).
At the moment, there is an increasing popularity in live dub groups (High Tone, Zenzile, Lab?, Improvisators Dub).
This new wave of bands are divided into different appellations: novodub, drum 'n' dub, dub newschool, dub hardcore, noisydub, technodub, heavydub, etc.
