The death of Amy Winehouse at age 27 caused an immediate outpouring of grief and love from the singer’s fans and from many celebrities, including Kelly Osbourne and Katy Perry.

Winehouse’s family has released a statement about her passing, the cause of which is still unknown: “She leaves a gaping hole in our lives. We are coming together to remember her and we would appreciate some privacy and space at this terrible time.”

Lady Gaga, who previously credited Winehouse with “opening the door for artists who dared to be different,” posted this message on Twitter: “Amy changed pop music forever, I remember knowing there was hope, and feeling not alone because of her. She lived jazz, she lived the blues.”

Russell Brand, who said he knew Winehouse “for years,” posted a heartfelt message on his Web site:

From her oddly dainty presence that voice, a voice that seemed not to come from her but from somewhere beyond even Billie and Ella, from the font of all greatness. A voice that was filled with such power and pain that it was at once entirely human yet laced with the divine. My ears, my mouth, my heart and mind all instantly opened. Winehouse. Winehouse? Winehouse! ... She wasn’t just some hapless wannabe, yet another [expletive] up nit who was never gonna make it, nor was she even a ten-a-penny-chanteuse enjoying her fifteen minutes. She was a [expletive] genius.

Soul group Sharon Jones and the Dap-Kings, who worked with Winehouse in the studio and on tour, released this statement:

We are very sad to have lost Amy Winehouse today. She was one of a kind and we were fortunate to have had the chance to make music with her. She was always gracious and a pleasure to work with in the studio and on the road. She brought a lot of people joy with her voice and her irreverent personality. It is a tragedy that she was taken from us so soon when she had much more music to give.

M.I.A. posted a previously unfinished track called “27” to her Twitter account, writing it is “dedicated to all my friends that died at 27.” You can listen to the song on Soundcloud here.

The song begins, “Said you’re all mouth and no brains/ All rock stars go to heaven/ You said you’ll be dead at 27/ When we drunk in a English tavern.”

Courtney Love, the wife of Kurt Cobain, also of the so-called 27 club, told Rolling Stone she is “gutted” by Winehouse’s death. “I’m not even going to say, ‘Waste of glorious sublime talent,’ which I feel.”
