Library music–also known as source music and, occasionally, mood music–was first made for people who needed cheap, somewhat generic music as backgrounds for animations, low-budget advertisements, and television programs. Unavailable commercially to the public, this music was pressed from the 1950s onwards in limited quantities, and then sent directly to production houses and radio stations for use when necessary. The Music Library is a compilation of cover artwork from some of the most important–and beautiful–library LPs made throughout the 50s, 60s and 70s, some of which retail for up to $2,000 today. Features record sleeves from the collections of Jerry Dammers (The Specials), Jonny Trunk (of Trunk Records), YMC, Luke Vibert, Steve Stasis, Jazzman Gerald, Lo Recordings, Intoxical, Julian House and The Reverend Martin Green. Compiled by Trunk–who also wrote the introduction–The Music Library features a foreword by Dammers and an exclusive CD of rare library recordings.
