Progressive house
Progressive house tunes often feature a build-up section which can last up to four minutes.  This is followed by a breakdown and then a climax. Elements drawn from the progressive rock genre include the use of extended or linked-movement tracks, more complexity and reflection but almost always within the four on the floor rhythm pattern.  The more experimental parts of house music are described as progressive. Detractors of the genre have described it as elitist and over-produced.
