it is pretty amazing to me that disco only lasted a mere 5 or so years. various other forms of dance music spawned from disco in the early 80’s, another 3 or 4 years. then comes electronic music from chicago and detroit, which certainly had disco roots itself, and this is still going strong after 25 years. i suppose the dance music genre finally morphed into something that within its standard, could consistently remain groundbreaking, without over commercializing itself and self imploding.
