Do you have any preferred genres?Some good progressive rock is old Genesis, like the albums Trespass and Nursery Cryme. Some good metal of course is Iron Maiden, Kreator is a great thrash band if you've never heard of them. Ween is a good sorda weird drug influenced band, so if you like weird shit they may be for you. Nirvana is good but I'm sure you've listened to them, and of course Iron Maiden.Theres so many more I could name but I'll leave it with that.
