I was going through some older releases by the likes of Elvis Presley, Johnny Cash, some of the old crooners, etc., and noticed a lot of recordings are missing a vocals credit. Is this just the result of ‘laziness,’ or is there a reason for it (e.g. avoiding redundancy; style guidelines; etc.).
Also, what’s the difference between “lead vocals” and “vocals”? I’m guessing lead vocals is when there is a backing vocal group, and vocals is if the singer is alone (or perhaps in a duet), correct?
