As as you sort of hint many bands are awful when you take away the studio production.
Yes live is great because it showcases how skilled they are. I love Zep and Page is amazing but IMO Howe is the best and most talented/skilled rock guitar player ever.
I am a HUGE fan of ELP and losing two of the three members last year means I won't get to see them again but I saw them a few times and it was always impressive. I saw them on the Works tour then a couple of times years later in small venues. Unparalleled in their skill and ability.
