There are tons of Euro progressive/power metal bands out there with singers like the ones from the old days. It's so much better than the 'growling' that passes for singing nowadays.
Sorry, but a talented growler is actually more impressive than a mediocre shrieker. You may not "care" for the style, but that's just your reaction.
That said, the metal community is full of shitty singers, both shriekers and growlers.
There are also some really good metal singers out there: Mikael Akerfeldt (growls), Devin Townsend (cheese metal squeals), Jens Kidman (growlish), etc. Devin is one of the most talented vocalists on Earth and he calls in Mike when he needs a growl. There is definitely technique to it. With poor technique, you can destroy your vocal chords.
