Hello! Thank you for uploading these Live videos! I usually don't attend concerts but thanks to this platform a lot of people can listen to these performances! Yeah, Willie Nelson's music is great! Bob Dylan's music is great! Unfortunately these two legends can't sing like they used to sing, yes, we all age and everything's going to degrade sooner or later but I can still feel the "emotions" when I listen to performances like these! I recently listened to a lot of Bob Dylan songs! I bought an old Bob Dylan vinyl album "Highway 61 revisited", fortunately in a good or good enough condition! Analog sound may not be as precise as digital sound, also has analog distortion, but to me it sounds warmer and more "round", often even more "alive" and "organic", not always, though! I also listened to special Bob Dylan cover (Bob Dylan cover in Japanese)! Do you listen to cassettes, reel to reel, vinyls, CDs etc...or do you prefer listening to music via the mp3 or the WAV format on RU-vid, bandcamp etc...? Live music should sound much better, though! More "real", "organic", "natural"... I don't know about the frequencies, though! It probably depends on the equipment (microphones, speakers etc...) Have a wonderful day! Greetings from Germany!
