Mo Ostin, who presided as a top executive at Warner Bros.-Reprise Records for more than three decades, during which the artist-friendly company enjoyed a glittering, hit-making run, died Sunday of natural causes. He was 95.

“Legendary music executive Mo Ostin passed away peacefully in his sleep last night at the age of 95,” said Warner Records’ co-chairman/CEO Aaron Bay-Schuck and co-chairman/COO Tom Corson. “Mo was one of the greatest record men of all time, and a prime architect of the modern music business. For Mo, it was always first and foremost about helping artists realize their vision. One of the pivotal figures in the evolution of Warner Music Group, in the 1960s Mo ushered Warner/Reprise Records into a golden era of revolutionary, culture-shifting artistry. Over his next three decades at the label, he remained a tireless champion of creative freedom, both for the talent he nurtured and the people who worked for him. Mo lived an extraordinary life doing what he loved, and he will be deeply missed throughout the industry he helped create, and by the countless artists and colleagues whom he inspired to be their best selves. On behalf of everyone at Warner, we want to thank Mo for everything he did, and for his inspiring belief in our bright future. Our condolences go out to his family at this difficult time.”
