We're in the process of auditioning vocalists, and our current technique is to send them some vocal-free tracks, give them a week, and see what they come up with. It's a great way to see the general lyric/melody-writing style of the vocalist, but it can't be the be-all/end-all of the audition. We need to really test his/her vocal ability, and the best thing I've come up with is cover tunes. Now, everybody has different ranges, styles, etc, so to it'd be beneficial if the vocalist could pick a song that really showcases his/her ability. On my way to lunch today, I considered using Rockband (the video game where you play plastic instruments, to those who aren't familiar) as a tool for having the vocalist pick out his/her song and really letting loose. Has anybody ever tried this or something similar with decent results? Does it sound like a good idea? I'd love to hear constructive criticisms as I've never had to audition a vocalist before. Thanks!
