Stein co-managed The Ramones during their 1970s heyday
The personal assistant to former Ramones manager Linda Stein has been sentenced to the maximum 25 years to life for beating her boss to death.
Natavia Lowery, 28, was also given almost three years for stealing $30,000 (£19,500) from her boss.
Stein was found dead at her Manhattan apartment on 30 October 2007 having died from blows to the head and neck.
Lowery initially denied any knowledge of the killing, blaming it on a masked stranger who told her not to report it.
She eventually gave a videotaped account of beating Stein to death after her employer badgered her about the pace of her work and blew cannabis smoke in her face.
The sentence means Lowery will serve a minimum of 25 years in prison before becoming eligible for parole.
Stein managed The Ramones along with Danny Fields during the band's heyday.
The ex-wife of Sire Records head Seymour Stein, she went into property after parting company with the band in 1980.
Dubbed a "broker to the stars", Stein's clients included Madonna, Sting, Steven Spielberg and Angelina Jolie.
