A musician arrested in connection with the death of actor Philip Seymour Hoffman toured with Wyclef Jean for 10 years and also worked with stars including Sir Tom Jones and Amy Winehouse.
Robert Vineberg was one of four people held following a raid on a New York apartment on Tuesday night while police continued to probe the source of heroin found at the late actor's home.
He has pleaded not guilty to a charge of felony possession of heroin with intent to supply, and it has since emerged Vineberg, 57, is a veteran musician who has performed with some of the world's top stars.
Using the stage name Robert Aaron, the Canadian played keyboards in Jean's backing band from 1998 to 2008 and contributed to Delilah hitmaker Jones's 2002 album Mr Jones.
He also played saxophone and flute on Winehouse's debut record Frank in 2003.
Vineberg and two other suspects are due back in court in New York on drug charges later in February. A fourth was released without charge on Wednesday.
Hoffman was found dead from a suspected drug overdose at his Manhattan apartment on Sunday.
