Margerine Eclipse by Stereolab

Margerine Eclipse is the eighth studio album by English-French avant-pop band Stereolab. It was first released on 27 January 2004 in the United States by Elektra Records and on 2 February 2004 in the United Kingdom by Duophonic Records. The album is in large part a eulogy to former band member Mary Hansen, who was killed in a cycling accident in 2002. Margerine Eclipse was mixed with full stereo separation (or as the band called it, "dual mono"), meaning that each instrumental or vocal part is hard-panned to appear in either the left or right channel only, much like early stereo albums by The Beatles. This technique was also used on its preceding EP Instant 0 in the Universe. As of June 2004, the album had sold over 40,000 copies in United States.
