Jerusalem and Dopesmoker are the third album by the American heavy metal band Sleep. The albums were released in 1999 and 2003 respectively. The music for these albums was written during a four-year period when the group was working on a single song that was around an hour in length. Sleep had signed with London Records, which financed the album. When recording had finished, London Records was unhappy with the finished product and refused to release it. The album was later released in various forms by different record labels. All versions of the album received very positive reception from music critics, who described it as a high-water mark in both the stoner metal and doom metal genres.
