(FILES) Brian Wilson, leader and co-founder of the rock band the Beach Boys, performs on the Pet Sounds: The Final Performances Tour at ACL Live on May 13, 2017 in Austin, Texas. Beach Boys founder Brian Wilson has been placed under a conservatorship by a Los Angeles judge, following his struggles with dementia and the recent loss of his wife. Wilson, 81, regarded by many as a singular musical genius, has required help with his daily life since his diagnosis, which was publicly revealed last year.
