Some now say that Adams’s rock-star patronage masked a darker reality. In interviews, seven women and more than a dozen associates described a pattern of manipulative behavior in which Adams dangled career opportunities while simultaneously pursuing female artists for sex. In some cases, they said, he would turn domineering and vengeful, jerking away his offers of support when spurned, and subjecting women to emotional and verbal abuse, and harassment in texts and on social media. The accounts have been corroborated by family members or friends who were present at the time, as well as by correspondence from Adams reviewed by The New York Times.
