In his latest song “Without You” Avicii is combining two music styles in one song: It starts as a vocal and acoustic guitar song and then builds up slowly to become an instrumental trance-style song at 2:27 min. Very cool idea.
For some reason the plucked octaves in “Without You” e.g. at 2:31 – 2:33 min. remind me of a Tella 2XLC remix of the song “Spring” from the German music producer RMB (Rolf Maier-Bode).
