I have seen Garrett Miles perform a few times and do not care for him at all. In my opinion, he has a fair voice and good enough selection of songs but he has absolutely no stage presence at all.
I would much rather see Lenny Wilson Trio, Sugar Bear Band, Yesterdayze, Uncle Bob's Rock Shop, Cactus Jack and the Cadillacs, or Rocky and the Rollers.
Heck, I would even listen to Carol Ann before listening to Garrett Miles.
Each to their own.
