The author appears confused as to what being a DJ actually involves. This confusion is understandable considering she seems to believe that the electronic music scene begins and ends with the Big Room EDM of Netsky/Flume. Whilst this may be the commercial face of EDM, for many fans it is no more representative of the EDM genre than chart Hip-Hop is of the Hip-Hop genre. The very idea that refined DJs would want "the platform occupied by cake-throwing pyrotechnic-firing entertainers" betrays her claim of understanding the scene.
Anyone can play some popular tracks and mix into the EDM scene for a while but that's not going to get you on the Resident Advisor Top 100. Serious DJ's (I'm talking the likes of Ricardo Villalobos or Nicolas Jaar) have a religious like commitment to the art and performing sets is only a fraction of what they do.
I think that backgammon is more similar to chess than poker in this respect. Despite the exogenous element of chance it can still be considered a perfect information game.
Your statement does not hold for games truly characterised by imperfect information (e.g. poker), in theory or in practice.
