Maybe some of you musicians or aficionados can help out here. I've seen various "making of (insert band here) album" documentaries over the years, and it seems that there's a couple of answers: 1- The whole band is performing at the same time in the same studio and a "live" take, mixed and/or edited (and extra instrument tracks, as necessary, are added later), is used for the album cut. It seems that all early Beatles, for instance, was done this way. The Pearl Jam documentary for "Yield" suggests that this was done for that album, and "Rattle & Hum" shows that the song "Desire" was recorded this way. 2- The entire band plays the basic track as a "live" cut, but the bandmembers are in different individual studios (not necessarily one for each) in the same building. 3- Different parts of the band lay down tracks separately, but possibly with two or more being played at the same time. For instance, drums and bass are recorded together, or maybe ALL the instruments together, and vocals are added later. 4- The instruments and vocals are all recorded separately. The documentary for U2's "The Unforgettable Fire" shows an example of this. Another example is something I read about the, ahem, "band" Power Station from the 80's, where not only were none of the instrument or vocal tracks recorded together, none of the "band members" ever even SAW each other during recording and the tracks were laid down in different studios in different countries. I don't know if there's anything that is considered "typical" of recorded rock music, anyone care to comment?
