Impeccably designed by Roger D’Arcy of Recording Architecture and equipped with an 80-channel Solid State Logic 9080 J series console, Black Rock had booked its first client, blues guitarist Joe Bonamassa in 2008, even before it had been completed. “He just saw the drawings!” says Kostas. That same year, it was named the world’s “Best New Sound Recording Studio” by Audio Pro International. Black Rock’s reputation quickly spread by word of mouth among recording artists, a trend that Kostas hopes will continue so that one day he may welcome his personal top three favorites – Muse, Timbaland and Rammstein – to the facilities.

As we are shown around the well-appointed, beautifully-lit villa with its beckoning swimming pool, we can’t help but wonder if we might be looking at the scene of some of those wild parties so often associated with rock legends. Alas, the truth is more mundane. Artists come here primarily to avoid distraction while working on their songs, and perhaps to visit one or two places on the island. Even Justin Bieber, the “bad boy” of pop, turned out to be sociable, friendly and – of course – a real pro. In fact, he left behind a gift for Santorini, a video clip that helped promote the island all over the world.
