Now you are dealing in semantics of what you describe as pop . All music other than classical is defined as popular music , Jazz , Folk , Pop , Rock etc . As to well recorded artists Richard Thompson , Colin Vearncombe , Yes , King Crimson , Madelaine Peyroux , Lyle Lovett , Yello , Malia , Fela Kuti , Sean Kuti , Salif Keita , Pointer Sisters , Steely Dan , Little Feat , The Beatles , Pink Floyd , Japan , Roxy Music , Grace Jones this is just a very small part there are really hundreds more . If you do not like electronic music then fine but that does not make it well recorded it just means it is not to your taste . Kraftwerk are a wonderful band and created a large body of well recorded and brilliant music . They did it using electronic instruments of an increasingly complex nature it is what they wanted to do . Your sweeping view all of this is rubbish is just not credible and even now you are listing people who make music recorded to your standards . I have no issue with individual artist moans and having a view that they are not recorded well but it needs to be that by artist . My Wife loves Sam Smith , I am not as keen but I do have to admit that his albums are very well recorded . I love Tom Waits and Captain Beefheart and my Wife does not , in both cases they have some very well recorded work and in others some not that well recorded but I still love the music .
If you are a mainly acoustic singer with a small backing then natural techniques may well be the way to go . Cassandra Wilson has quite a few albums which show this off Belly of The Sun being one of them . However if you are ZZ Top , Prodigy , Motorhead , or Philip Glass then natural techniques just will not work . The Blue Nile first and second album show what can be done . First album has all real instruments either acoustic or electric (I consider electric guitar and bass to be real) . The second album is almost all electric . The emotion and quality of the music is really high on both albums and the recordings while very different are each excellent with soundstage , and air . It is the music that is what matters I do not listen to any music just for the recording I listen to the music .
