Brian Wilson (1942-2025). American songwriter and producer (Beach Boys) whose innovations in studio production, harmonic complexity, and orchestration reshaped popular music in the 1960s and beyond. Wilson was diagnosed with schizoaffective disorder and lived with auditory hallucinations for most of his adult life. His cognitive signature is the discovery specialty operating in service of an unusual sonic intuition — he heard arrangements internally before recording them, with a level of compositional detail his collaborators could not match — and the production work on Pet Sounds (1966) and the unfinished Smile sessions established a new standard for what popular records could be. The integration partner was the Beach Boys themselves (his brothers and cousin) and the surrounding studio musicians (the Wrecking Crew) who could play what he was hearing, plus producer-engineer collaborators who could capture it. Wilson's mental health collapsed in the late 1960s and his recovery took decades; he produced significant work into the 2000s. The pattern: the discovery specialty operating at peak intensity in a body that the discovery specialty's intensity was costing.
