===Evolution of dub as a subgenre (1970s)===
By 1973, through the efforts of several independent and competitive innovators, engineers, and producers, instrumental reggae "versions" from various studios had evolved into "dub" as a subgenre of reggae.

The innovative album ''The Undertaker'' by [[Derrick Harriott]] and the Crystallites, engineered by [[Errol Thompson (audio engineer)|Errol Thompson]] and with "Sound Effects" credited to Derrick Harriott, was one of the first strictly instrumental reggae albums on its release in 1970.

In 1973, at least three producers, Lee "Scratch" Perry and the Aquarius studio engineer/producer team of [[Herman Chin Loy]] and [[Errol Thompson (audio engineer)|Errol Thompson]] simultaneously recognized that there was an active market for this new "dub" sound and consequently they started to release the first albums strictly consisting of dub. In the spring of 1973, Lee "Scratch" Perry released ''[[Upsetters 14 Dub Blackboard Jungle]]'', mixed in collaboration with [[King Tubby]] and more commonly known as "Blackboard Jungle Dub". It is considered a landmark recording of this genre.<ref>David Katz, sleeve notes of Auralux reissue of Upsetters 14 Dub Blackboard Jungle, 2004</ref>

In 1974, [[Keith Hudson]] released his classic ''[[Pick a Dub]]'', widely considered to have been the first deliberately thematic dub album, with tracks specifically mixed in the dub style for the purpose of appearing together on an LP, and King Tubby released his two debut albums ''At the Grass Roots of Dub'' and ''Surrounded by the Dreads at the National Arena''.
