Deep House Radio, in the late 80's the sound split into many sub-genres because the term “house music” became many things to many people. Much of the world associated house as either Euro-led trance, or Hard House – a purer electronic, and less melodic sound favored by some mainstream radio stations and known DJs.. Deep House Radio commonly appeared as a genre in the early 90's, describing a more melodic, stylish sound with influences from soul, jazz and African beats, with many of the earlier tracks being sampled chords and beats. The jazzy sound became more apparent due to the favored use of electronic pianos such as the Fender Rhodes, Wurlitzer and Hammond B3 organ. Examples of well known Deep House Radio artists and producers include Kerri Chandler, Joe Claussell, Mateo & Matos, Roland Clark and Ron Trent. Some of the early record labels included Henry Street, Nervous Records, King Street, etc. In more recent years Deep House Radio tends to refer to tracks on the “spacier” side of Soulful House and tends to imply less vocals, deeper tones, heavy organ chords and hypnotic synth sounds. It originated in the 1980s, initially fusing elements of Chicago house with 1980s jazz-funk and touches of soul music. Deep house tracks generally have a tempo of between 120 and 125 beats per minute (BPM).
