A significant percentage of history’s greatest composers, musicians, writers, and painters had severe mental and/or emotional problems, as well as drink and drug problems. Some of them created in spite of it, some because of it. That’s not my opinion, that’s history’s. Smile is in no way worth the suffering Brian has endured (not to mention his family, friends, and The Beach Boys themselves) because of the LSD and other drugs he took to excess. But he had already had a nervous breakdown before his drug use started, on an airplane flight in late 1964. That was one reason he came off the road, and stayed home writing and recording while the others toured.
But there is nothing we can do to turn back time, to change the circumstances of Brian Wilsons decisions. Should we deprive ourselves of great art because of the price it cost it’s creator? You do what you want---I’m going to continue to listen to Smile and Brian Wilson’s other masterpieces, and to tell others who are interested all about it.
In case you want to investigate, The Beach Boys also created some great music in the 1970’s, starting with the Sunflower album. Brian wrote some of his best songs in the 70’s---"This Whole World", "Til I Die", "Marcella", and "Sail On, Sailor" being just a few. Yeah, The Beach Boys (as led by Mike Love) are a nostalgia act now, but they weren’t then. Dylan saw them and said "Hey, these guys are really good". The Grateful Dead toured with them.
