Absolutely right...I think criticism was directed at them because they were popular, successful and others in the industry were jealous...pure and simple. They provided a sound and an energy which people bought into which others in the industry couldn't handle. While people were buying SAW records, they weren't buying other records. They were also one of the first production teams to become famous to. Before, producers stayed mainly in the background.
I totally agree with you on the whole "real music needs guitars" lark. I loathe it to. It is a very simplistic and narrow minded view to hold that this is "real, proper" music but this isn't...purely and simply because of the way a record is produced.
Their music is totally fun to sing and dance to.
I have done a few megamixes...if you would like to have a listen to them, I could PM them to you...
As well as writing original songs, they also provided remixing services to...here are some examples...
