I've seen Avicii twice so far at Ocean Club (fucking guido central) and at Identity Festival. He played the same exact set. He's only decent at producing, and much of his stuff isn't as original (almost all of his melodies are taken from something else), he also doesn't really make his own sounds. For example, if you have the Sylenth VST, use the Punchy Arp preset and voila you have Avicii's bassline (without changing anything AT ALL). As a producer it's frustrating in some sense because that's not really his work that he is using.
It's just frustrating that you start to hate music when people you hate start to like it for the wrong reasons. Because they don't really appreciate the music for what it is, but because other people like it, they don't understand the differences between genres or BPM or whatever, only just "Oh ya bro that shits dope". DERP
He is blowing up, making a name for himself, and making money, so I have to respect that. But as a producer myself I feel that there are many other producers that are not getting the attention they deserve.
Feed Me, Lazy Rich, Porter Robinson, Wolfgang Gartner, Adam K, Funkagenda, Felguk, Darth&Vader, Madeon, Chris Lake, DirtyLoud, Jack Beats ETC. All are better than Avicii IMHO.
For those of you saying EDM is at its peak, LOL. Kaskade was just on MTV (as lame as that it). And Deadmau5 just played a record breaking set in Toronto. Shits still blowing up. Go on beatport or soundcloud and listen to all the great artists that have yet to go big.
