Harry Manfredini

Harry Manfredini (born 25 August 1943 in Chicago, Illinois, USA) is an American film composer and jazz soloist who has scored more than one hundred films. He is probably best known for composing the score of nine of the Friday the 13th slasher films including the 1980 original. Manfredini also scored a number of other Sean S. Cunningham productions including Here Come the Tigers (1978), Manny's Orphans (1978), Spring Break (1983), the House series (1985-1992) and Deep Star Six (1989). Other credits include the Wes Craven films Swamp Thing (1982), The Hills Have Eyes Part II (1985) and Wishmaster (1997).

I bought the signed CD of the Friday the 13th Part 2 & 3 score directly from the La-La Land Records online store.
