I’m talking not only every studio album, but every live album. Bands that you will pay premium prices on overseas releases to get a listen to one particular version of one particular song. You will buy out of print stuff on ebay. The kind of band you will travel thousands of kilometers to see live. That kind of band.

For me, the answer is the British band Caravan, who have tapered off in their studio albums (only two in the last decade) but still actively tour.
