One of the first progressive house records according to discogs. It's interesting it has a trance bassline but the chord has a house sound with the piano sound
for 'House' music is 'Chicago House' the fundamental ground.. soulful, sometimes deep, sometimes jazzy, but mostly very black music. Black in the sense that it sounds like its made by black musicians. think of 'Mr Fingers', 'Kerri Chandler', 'Chez Damier' etc etc
when guys in the UK and in Italy started producing 'House' music on their on way, their sound was naturaly very different, so most of the 'House' music without the -black- feeling of 'Chicago' or 'Detroit' was called 'Progressive'
we can also say 'Progressive House' is the European 'House' music
