Would it be nice if artists sell master cassettes or tapes of a performance

For example:


A pianist players adagio on piano recorded direct to a cassette recorder


The super quality direct sound recorded cassette is sold on eBay. Note: it is not at all easy to make good quality recordings. The microphone dies not have a brain. There should be low and high frequency absorbers in the recording room to minimisei reflections of sound to the microphone. Each instrument should preferable be closed miked etc.


The artist does not have the master anymore. Like painting selling.
