I've got a bunch of the old "bachelor pad" aka "space music" collections from the 60s; many of them feature hard-panned instruments. Has nothing to do with live sound, but was fun for the pipe-smoking sophisticat trying to bed a sweet young thing by impressing her with the size of his "hifi".
What tracks offer the best left right separation?
Separation is a big part of a live performance. Name your medium streaming, turntable you name it but the key. Is the track you listen to and the separation you get.
