I second that. The 1970 shows are great, especially those mentioned. The same can easily be said about the rest of their audience recordings. Great quality, some even better than certain soundboards.
If you were to buy four, I would recommend
On the Road Again
Shining in Portland
Something Old, Something New
It’s Now – or Never
First two are volumes 1 & 2 in their West Coast Tour series. There may not be a volume 3. Anyway, they belong together. Old/New is the opening show from the January/February 1974 Vegas engagement and is an absolute must for an Elvis concert lover. All opening and closing shows are essential, in my opinion. The last CD contains a good show in great sound.
I have written SHORT reviews of some of these CDs here:
More to follow on that site when I’m in the mood.
