Before the Beach Boys began to work on Smile, Brian Wilson was already expanding his mind with the aid of LSD. The drug proved to be a point of contention with other band members, who bristled at Brian's newfound mind-altering methodology. Brian's LSD intake didn't just spark arguments between the Beach Boys. LSD made a black-and-white appear in Technicolor for the first time. It made water taste like it fell straight from heaven. It made musical notation come alive, notes and staffs just floating in the air. But LSD also brought with it a rising feeling of anxiety. The walls got bigger. Every room was suffocating. And before too long...the voices began to speak inside Brian's head.
