There is no specific figure that influences me at most! When I was little I loved Dj Conne and Tiesto now there's so many of them Avicii has great melodies, sounds, vocals and lyrics to his songs that makes him amazing!
Then Armin van Buuren keeps the pace to produce quality music, while Henry Krinkle producing amazing deep sounds. Dusky keep pushing his productions, when Disclousure and Nicky Romero breaking through. But cannot forget about David Guetta and Afrojack who pushed the electro house to the mainstream. But if we not talking about mainstream we have Laidback Luke. I think is good to look at as many artists as we can, either from underground or mainsteam.
