I got involved with a singer who is rebuilding a band he had until 2017 or so. He recorded three CDs between 2012 and 2016 and his voice sounds good on the recordings. But, during recent rehearsals, his vocal intonation is all over the place. So is his slide guitar playing. When I comment about the latter, he sheepishly says "I know - I'll focus better." He's 73 years old, wears hearing aids and uses a Shure headphone/mic combo.
He has 3 gigs booked beginning in early June. As an audience member, I would walk out of a performance if someone sang this badly. As I've gotten older, that sort of thing has only become more irritating, so I can't envision being a member of a band and having to put up with it.
How do you tell someone they need to do something drastic, like:
1) Work on the technology you own and see if it helps. Do it by next week.
2) Give up singing and end the band.
I'm open to other solutions. I could just walk away, but rehearsals are in the middle of nowhere, so it's practically impossible for him to attract players.
