I'm looking for some 60's-70's Classic Hard Rock recommendations that are similar to this song: http://www.youtube.com/watch?v=4ildurwJPfQ
I'm trying to think of bands with vocalists who are between singing and screaming. In other words, they really unleash the vocals and are somewhat epic sounding. The Who, CCR, and Led Zeppelin come to mind but what are some other bands? I also love the bass tone and the drums in the aforementioned song. Any recommendations?
