Uriah Heep is one of my favourite bands yet they are unknown to many people. Some of their songs would be so great to play on Rock Band, the guitar solos, the keys, the drumming and the vocals are all so intense.
There are, to my knowledge, at least 2 re-recordings of many of their songs with a different singer. The originals are the best so I'll list the album they are from in brackets (or parenthesis if you're American).
Lady In Black (Salisbury)
Too Scared To Run (Abominog)
Circle Of Hands (Demons and Wizards)
Look At Yourself (Look At Yourself)
July Morning (Look At Yourself)
Tears In My Eyes (Look At Yourself)
Stealin' (Sweet Freedom)
Gypsy (Very 'Eavy, Very 'Umble)
Return To Fantasy (Return To Fantasy)
Bird Of Prey (Salisbury)
Easy Livin' (Demons and Wizards)
