Hey gang,

As many of you saw on MetalUnderground.com yesterday, we announced that next week we'll be releasing all of Judas Priest's classic metal album British Steel. These tracks are live recordings taken from their 2009 tour, where Rob Halford and co. proved that, even after 30 years, they've still got the goods. Dig in, enjoy, and keep posted for the RBN DLC announcements at 11am.

“Breaking the Law (Live)” +

Hopefully live tracks means some sweet long Big Rock Endings.

Not really my genre of music, but I do like the few Judas Priest songs that I've played on Rock Band (save for Painkiller, never understood why that was so popular). I'll give these a listen.

" save for Painkiller  , never understood why that was so popular"

Wow, so the mixing is terrible.  Stay away!  Stay far, far away!

Because it's one of the hardest Rock Band 2 disc songs. "
