In a recording studio with a smaller recording space, there is probably not enough room to set the entire band up at once. Even in a medium-sized room the set-up may be cramped, uncomfortable, and not conducive to a great performance. Bands usually play better when they perform together and can hear all the parts they are used to hearing, the musicians can gel and groove, instantaneously feeding off each other’s energy and musicality. For most rock and pop projects the vocals are usually the focal point, and must be 100 percent correct, so it’s best to overdub them after the rest of the music has been recorded. In a multi-room or home studio, it may be possible to record a band all at the same time, and maintain isolation between the different instruments by putting them in different rooms.
