You mean sounding as though someone has recorded it with a portable cassette recorder at the bar, where you can hear the conversation of those around the recordist better than you can hear the group or artist(s) on stage?
Modern live recordings are so much better than they were in the '70s - no more endless audience applause and rapture; no more badly positioned mics; no more lousy mixing ....., and IMO they do now capture the atmosphere and acoustic of the performance and venue.
