Suppose a band has just been signed to a record contract and they are going to a nice recording studio to record their album. They're trying to get the album recorded reasonably quickly.
if they're in the studio for 8 or 12 hours, or however long is typical, how much of that time would the lead vocalist actually be singing on a day when they're recording lead vocals?
Taking into account things like double or triple tracking and doing harmony parts, how many hours might a lead vocalist be expected to sing in one day?
Would that vocalist be expected to sing as long the next day and the day after that for a lot of days or would they likely record guitars or bass the next day to give the singer a break if he had to sing a lot of hours?
What would be considered "a lot of hours" for a lead vocalist of a hard rock or metal band in the studio?
