|The Slaughterhouse (subtitled Trax from the NPG Music Club Volume Two) is the 30th full-length studio album by Prince and is the second compilation album of NPG Music Club downloads from 2001-2; a companion piece to The Chocolate Invasion (released on the same day). Four tracks are edits or alternate versions to those previously-released.
No singles were released from the album at the time of release (although Peace and The Daisy Chain, both credited to the New Power Generation, had been sold at shows on the Hit N Run Tour in 2001). The album was not eligible for the charts, as it was available only through the NPG Music Club.
Specific recording dates are not known, but it is believed that most of the tracks were recorded between late 1999 and 2001 at Paisley Park Studios, Chanhassen, MN, USA. Peace, 2045: Radical Man and Northside were at one point considered for the album Peace, by the New Power Generation, which was advertised on NPGOnlineLtd.com upon its launch in March, 2000, before being abandoned.
Golden Parachute and The Daisy Chain were at one point considered for the album High, which was completed in late Summer, 2000, before being abandoned. Instead, the tracks were released on an individual basis on the NPG Music Club (2045: Radical Man was released separately on the Bamboozled soundtrack album in 2000, credited to Prince).
In 2003, the album was planned for inclusion as part of the The Chocolate Invasion 7 CD set, which was put on hold indefinitely in late 2003, officially due to a manufacturing problem.
Notably, S&M Groove and Hypnoparadise were originally released using the name , while Northside, Peace, 2045: Radical Man and The Daisy Chain had all been previously released under the name New Power Generation (although 2045: Radical Man was first released under the name Prince). This collection does not credit tracks at all, but the album is considered here as a "Prince" release.
