My personal favorite I have mentioned here before is Crack The Sky. They were a bit different, some Beatles influence, they melded alot of styles and influences, sometimes quirky, sometimes heavy, great tangents thrown into the middle of many of their songs, sometimes even having a Broadway feel and/or sense of expression . Their first (ST- '75) and third (Safety in Numbers '78) albums I think were great, the second (Animal Notes) I like alot but it had to grow on me, probably the most Beatlesque.
Check them out on youtube if you want. I'd stick with the studio versions as any new footage is cheap and sounds like shit. Polumbo changed his vocal style and his voice isnt that great anymore. They did release a great live album back around 78 that proved they could get the job done but I dont see it in recent years. Kansas threw them off thier tour because they stole the crowd and I love Kansas, so thats saying alot.
All that said Im more into Kansas, Rush, CTS, Tull and the more progressive moments of early Alice Cooper than King Crimson, ELP, Yes and Genesis, not that I dont like them.
Heres Nuclear Apathy from Saftey in Numbers, if you have good sound from your computer unlike this laptop Im using, better yet try headphones, check out the bass work and bass/drum interchange. This gets pretty heavy dont let it fool you,the chromatic instrumental bridge was awesome in its day
