 The group and Botnick organized a makeshift recording studio at their private rehearsal space , The Doors ' Workshop , in a two @-@ story building at 8512 Santa Monica Boulevard , Los Angeles They could then record in a more comfortable and relaxed setting while avoiding the expenses of a professional studio . A mixing console , previously owned by Elektra , was installed in upstairs in the Workshop , while studio monitors , microphones , and keyboards were set downstairs . To compensate for the lack of an isolated vocal booth , Morrison recorded in the bathroom , singing into the same microphone as used on the Doors ' final tour .
