Ruth Flowers (29 March 1931 – 27 May 2014), also known as Mamy Rock, was a British DJ and record producer.

Immediately seduced by the lively and energetic atmosphere reminiscent of her youth, Flowers started to joke with her grandson that she too could become a DJ.

She was then introduced to a young French producer, Aurélien Simon, whose musical project caught her enthusiasm.

She progressively began to develop her own mixing style, with influences from some of her favorite artists, including Freddie Mercury, The Black Eyed Peas, and several other top names in the music business.

Her first gig was in front of a crowd of celebrities such as Lenny Kravitz and Mariah Carey, during the 2009 Cannes Film Festival, at the Villa Murano.
