These days I've discovered a new great artist thanks to Spotify. His name is Parov Stelar and his music it's absolutely gorgeous.
Stelar started to play as a DJ during the 90s and then he created his own label in 2004, the "Etage Noir Recordings". He's defined as the creator of Electro Swing. This genre combines the swing with the sound of electro, generating a new kind of music. I would define it in three words: relaxing, energizing and classy.
He's in my opinion a must-listen-artist.
