"We are very sad to lose such a talented person in our industry," Mark Birnbaum and Eugene Remm, partners of the EMM Group, whose nightlife empire includes Tenjune, told PEOPLE in a statement. "He will be missed and this is a terrible loss for all of us."
It was Goldstein who deejayed at Tenjune's opening party three years ago on Saturday, Aug. 29.
Michael Satsky, an owner in Lily Pond nightclub in East Hampton and the now-shuttered Manhattan club Stereo, where Goldstein deejayed prior to its closing in 2008, tells PEOPLE, "The higher powers have taken one of the 'greats.' "
Describing Goldstein's appeal, Satsky said, "So many have been deeply touched by his greatest talent, helping people. I lost a dear friend and a brother in many ways. If you were close [to] Adam, then he was always your No. 1 phone call in precarious moments."
Scott Sartiano, a partner in New York hot spots 1OAK and Butter (Goldstein deejayed a Butter party in St Tropez three weeks ago), tells PEOPLE, "Adam was not just a world-class deejay, he was also a world-class person and friend. He made a difference in our lives, and his memory will live on forever."
A Friend Who Reached OutRichie Akiva, another partner in 1OAK and Butter, says, "Adam was an amazing person and talent who touched many people around him with his heart and soul. He was a dear friend and will be very missed."
And Noel Ashman, a nightclub vet whose club roster includes the former Manhattan spots Veruka, NA and The Plumm, recalls meeting Goldstein more than a decade ago after mutual friend Mark Ronson suggested Ashman spin at Veruka.
"I said, 'Sure. But can he hold the room?' – and he just killed it," remembers Ashman. "And he was so appreciative about it. He came up to me like nine times and said, 'Thank you for giving me the chance to do this in New York.' "
Adds Ashman, "Even when he became famous, he never had an attitude. He was a humble, really, really nice guy. He was someone who really cared about his friends. He was a solid, solid guy. He never changed, even after he became well-known."
Goldstein was a partner in Dusk, a nightclub at Caesars in Atlantic City, which closed Friday night in his honor. (It re-opened Saturday.) A spokesperson for the club – where Goldstein deejayed last Tuesday and Saturday – said, "We are devastated by the loss … He was a true talent who will be greatly missed."
