>>4 I can't disagree that house is becoming a lot more generic. I wouldn't criticize all EDM as lessening in variety, though. There are many, many artists that are quite unique, but there are also many that are not. It depends on where you look. I also think house is becoming more popular, and a lot of 'pop' songs I hear are house, which may contribute to the decline in variety.
However, I believe Mord Fustang is sufficiently unique. It is in large part because he is from a different country that does not have a lot of popular EDM producers, so even if he sounds like a lot of artists from Estonia, I would never know. I think the intros to his songs all sound the same, and the structure to each song is similar, but I think the rest of the song is different enough from the next. He may not be a pioneer, but I think he's talented.
Also, this may not be universally true for house, but I enjoy that repetitive base structure. There's not much variety there, but there doesn't have to be for me because I enjoy it. There's enough variety elsewhere to make each song enjoyable. In this same sense, something like that may apply to indie rock. I can't really find the quality in it, sadly. I know it's there, many people enjoy, but I can't get into it. That may be different in 20 years, I don't know.
I also couldn't find your post on EDM.
