What band have you "discovered" on RS that have particularly impressed you?
For me it's Little Barrie, I never heard of them before but have now gotten all three of their albums and think they're really excellent. Sadly they're not touring right now but if they're ever close by then I'll be there and I'd love to see more songs from them available as DLC.
I have also discovered that I far prefer playing Megadeth to listening to them. Which is probably an odd thing to say but there ya go.
