What follows is a guest post by Jay Miller. One of the great legends of heavy metal music history goes like this:  In the early 1990s, a little known three-piece band from San Jose, California named Sleep worked out a deal with London Records to produce their third album, Jerusalem, which included the rare luxury of maintaining full creative control. Instead, they blew most of the $75,000 advance on custom guitars, high-end amplifiers, and lots of marijuana. During two month-long recording sessions, they recorded a single, hour-long song filled with slow, churning guitars and monotonic chants having something to do with a new race of “Weedians.” Throughout the recording process, the song (which in various forms the band had played live for several years) evolved: it got longer; and, in the words of bassist Matt Pike “It got weird.”
