I think I should refrain from critiques of members playing arrangers because, as performance tools, I don't like them and don't use them.
The only one I really enjoy is Don because of the way he injects his personality into his performances and his unique way of emulating a slide steel guitar.
I do use arrangers for film roughs and consider them to be indispensable for those.
What I like about Don's work is not the arranger at all, but the vocal, guitar and rapport with the audience.
Chas is a killer player, in spite of what he says. He only uses an arranger for the drum machine. With him, I like his arrangements, changes and pure, historic B-3 tone. He's a stylist and a good one.
Lot's of others are better entertainers than musicians, and that's hard to demonstrate on a recording. I'm not an entertainer and really don't want to be, so those submissions, while appreciated for the effort, really don't do much for me.
I will say that there is no excuse for bad changes, and inflated egos are a real turn-off.
Those do pop up occasionally, here, and I just try to bite my lip.
Be well, all,
Russ
