this song was recorded in 1959, and the recording quality of it is amazing compared to almost everything else recorded before the 70s. the only part that "sounds old" is the snare. the vocals sound like they're probably old, but they're too sparse and background-sounding to be sure, which makes me wonder if a big part of the reason that stuff sounded old is that they set the gain higher back then
this is was recorded in 1971, has much more going on, uses many sounds that did not exist when comanche was made, but it SOUNDS much older because of the sound quality of it all. everything has a sort of grainy sound to it like the aural equivalent of all the lines and dots that flash up on screen when you watch older films
there are some songs like all i wanna do and del shannon's runaway where i think the only reason you can immediately tell what era it was recorded in is the general recording quality. the saxophone in runaway is a bit of a giveaway too, but you know what i mean. shut up
