Made To Play label founder Jesse Rose and Brobot boss Junior Sanchez are asking for people to come forward with information after they were targetted by thieves in Ibiza on Saturday (September 5).
Amongst the belongings taken from a car outside the Balafia restaurant were the pair's laptops, USBs and hard drives containing unreleased music of great personal value.
Posting about the incident on Twitter Jesse Rose wrote, "This is beyond a worst nightmare. I'm trying to hold my head up but I'm properly depleted. Possessions don't mean so much but my music is everything."
Anyone with any information is urged to come forward. Rose revealed, "I'm offering a serious reward for anyone who can give info or my stuff back, no questions asked, just want my music!"
Sanchez added "all we care about is our music and drives."
