Strahil Velchev loves it, doesn't he? Just look at him go . He can barely suppress a grin as he plays his basslines and furiously taps rhythms. When he drops the kick drum, his upper body seems to thrust involuntarily. He has the air of someone who's been practicing in his bedroom for years, and is itching to show you what he's got. Even when he's not out on the road performing, he's back at home performing: Velchev regularly tapes himself improvising on different setups and uploads the footage to YouTube . And check the image on his RA artist page —it's as if he can't get close enough to his machines. Velchev is very clearly a man who's infatuated with his craft.Why has he hit #1 in 2015? Well, it feels like word has finally reached everyone. Although he's appeared on this list four times, with three consecutive top-five finishes, Velchev just isn't what you'd call a stage-managed artist. He hops from label to label, and he's never been associated with a fashionable scene or sound. In the excellent " Cloud Generator " he had a hit track this year, but then that's the case most years for Velchev. The explanation is therefore quite simple: he's extremely talented, and in 2015 more people than ever took notice.
