There is more than one band with the name Knowledge:

(1) A Hip-Hop artist from Skelmersdale, UK, part of the Hip-Hop group SPS.

(2) Knowledge were formed by Link 80 lead singer Nick Traina (The Son of Daneile Steel, who wrote a Biography about him called "His Bright light"). Before the death of Nick Traina in 1997, they recorded one demo album called 'Gift Before I Go', which was released on Asian Man Records.

(3) The hard-roots reggae vocal group Knowledge, recorded the 'Hail Dread' album for Tappa Zukie in 1978. It was released by A&M UK, but inappropriately marketed. The album consequently failed to attract the attention of reggae collectors and is, today, a largely unrecognised classic of the genre.

The original line-up consisted of singer/songwriter Anthony Doyley and Michael Smith on guitar with Earl McFarlane, Michael Samuels and Delroy Fawlin on vocals.

‘Hail Dread’ was followed by ‘Judgement’. Selected tracks from both albums are available on ‘Straight Outta Trenchtown: 1975-1980’

The next decade saw the release of further recordings, although by this time several of the group had met violent ends.
