After thinking about it last night while listening to GRAND FUNK RAILROAD LIVE from 1969 here is another 5 live albums that are worth considering?.
1.Focus Live At The Rainbow (the Rainbow theatre in 1973 or originally called the Finsbury Park Astoria in north London but nowadays it's a Muslim temple)
2.Grand Funk Railroad Live (from 1969)
3.Motorhead No Sleep Till Hammersmith (from 1980)
4.Judus Priest Unleashed In The East (from 1979)
5.Wishbone Ash Live Dates Two (from 1979-80 possibly not as good as Live Dates from 1973 but it's a ok listen although I haven't heard it now for about 30+ years??).
I'm listening to all of my Focus albums today - going to see them on Sunday night.
