http://en.wikipedia.org/wiki/Siamese_DreamAfter he suffered a nervous breakdown, Corgan began visiting a therapist. Consequently his lyrics became more explicit about his troubled past and his insecurities.<6> "Today" was the first song written by Corgan for Siamese Dream.<5> He played the self-recorded demo to Vig, and received a positive reaction.<5> Soon afterward, executives from Virgin Records came to observe the band after hearing about their problems, but were pleased with the demo and did not soon return to the studio.<5> The reaction from the executives only served to put more stress on Corgan.<2> Corgan worked overtime, practically living in the studio for the recording of Siamese Dream—he and Vig would sometimes work on a 45-second section of music for two days, working 16-hour days for weeks at a time to achieve the sound Corgan wanted.<7>
Corgan's desire for musical perfection put further strain on the already-frayed relationships between the band members. Vig later recalled, "D'arcy would lock herself in the bathroom, James wouldn't say anything, or Billy would lock himself in the control room." Corgan often overdubbed Iha's and Wretzky's parts with his own playing.<6> Wretzky stated that Corgan only performed most of the guitar and bass parts because he could lay them down in recording easier and with far fewer takes.<7> While Chamberlin performed all drum parts on the album, he would disappear for days on drug benders that caused everyone to fear for his life. After one incident where the drummer had disappeared for two or three days, Corgan "put the hammer down", according to Vig, and had Chamberlin perform the drum part for "Cherub Rock" until his hands bled.<6> Due to Corgan's urging, Chamberlin checked into a rehab clinic.<7> Corgan told Spin later that year, "You know, I gave them a year and a half to prepare for this record... I'm surrounded by these people who I care about very much, yet they continue to keep failing me." Corgan explained that he began to take the actions of others personally; he said, "If you really think about it, of course, someone doesn't do the job because they're lazy, or they don't think it's important. But I took it as, 'You're not worth going home and working on the song
