One of my favorite K'ISS songs has always been 100,000 Years (ALIVE version) Absolutely killer drive on that one.
I've recently seen a few live versions from the 70's on YT and sometimes Simmons starts out too slow and it kills it. Slower versions have a draaaaag that the up tempo versions do not have. I haven't mapped out the proper speed but it is one of those numbers that rises or falls on how he/Gene starts sets the table.
BTW there are quite a few full concerts out now but you likely know that. Some of them grainy as hell but still... not too bad.
