Techno is more rapid and fast, but uses electronics well. laughed at for the 90s hysteria of crap pop music.
DO NOT GET IT MIXED UP WITH POP.
Trance is more musical and slower, which makes it very classical.
hard house is probably the greatest of them all, with fast tempo, great sounds and amazing climaxes.
Hard Dance is so much faster than all of the above, making it harder for beginners to the genre.
Rave, the dying genre, can range from slow, relaxing music to fast bumping sounds. some would say it relies too much on repitition.
Its best to start from this order to really enjoy the music, otherwise youll think youve wasted a good 15 quid on a CD, while hardcore fans will relish such a CD.
You dont have to take drugs, you dont have to be a hard-nut, you dont have to go about wearing massive trousers, you just want to listen to the music, and have a good time.
Enjoy. All people welcome.
