“The maestro has passed — the man was a open heart with two legs — with an ear that heard the angels. Quite literally. Love and Mercy for you and yours tonight. RIP Brian.” — John Cusack, who played Wilson in the 2014 biopic “Love & Mercy,” on X.

Wilson, who died Wednesday at 82, was one of music’s true visionaries, if that’s the right word for a guy who dealt in the endless possibility of sound.
