Interesting but hmm? Yeah I know what live music sounds like. Having played in bands for 20 years of my life including, marching bands, attending many acoustic shows, jamming with nothing but guitars a drum or maybe even just drum sticks or a bongo maybe a sax and a piano no amps yup I do . That also being said also palying through amps attending well over 1000 live shows or even 2000 counting bar bands local players, piano bars etc... yes I know what i am listening for.
Also why cant amplified music still be live music? Whay does live music mean no apmplication ? What we all strive to reproduce is the sound we hear seeing a live show so what sthe issues if its amplified? I really do not agree with the premise of that whole article.
Maybe thats the key, to know what you are listening for amplified or not . I can tell if its sounds close to live or as reasltic as it can be or just music coming through a speaker.
