Thanks for taking the time to pick up the thread of this conversation, Mudd -- I read your musings with interest.
Springsteen's Nebraska was recorded on a cassette porta-studio; Dylan's early 90's albums "Good As I Been To You" and "World Gone Wrong"
were allegedly recorded on a boom box, because Dylan thought the tape saturation and naturally occurring distortion made the collection of covers
sound more vintage.
It's funny...my aforementioned friend and I recently recorded a couple dozen tracks (long distance) of sort of garage/surf stuff. We strictly used 30 year old cassette 4 tracks. My buddy laid down drums (in his garage with two cheap realistic mics into his tape 4 track) and guitar(s), then sent me the tape, I added bass (one take!)
I'm dumping one of the tracks below, but we took a lot of our tunes and shoved them into playlists that included a lot of original old 50s/60s rock/surf instros, and they fit in seamlessly, as far as the actual "sound" of the recording itself, at least to our ears...
