List is to dump a bunch of my favorite metal bands that I've only discovered in the last 5-10 years. Most of these bands I found through Sputnik, it's the site that keeps giving for music discovery.
Top 10 in (somewhat) order. After that it's just a bunch of other awesome bands.
Album listed is the one that really got me into the band and is under 10 years old. Most of the albums listed were a gateway to the rest of the bands discography.
