I agree.
I obsess so much about getting the timing absolutely perfect and for each note to be always played consistently (volume an all) and then you listen to isolated tracks and realise even the "pros" don't get it perfect (to be fair, Sting was never a bass virtuoso, he's a technically average player who wrote very tasty bass lines). This video led me to Duran Duran Rio's Isolated bass track, a bassline i've played a lot, and that i felt i never played as well as Taylor. But listening to the isolated track, i feel i might have (on a few note he's a bit ahead) . It's not a diss on him. It just makes me feel better about myself and makes me feel i might sometimes set a too high and unreasonable standard for myself. No player is a robot. At least not many of them anyway..its possible a very small % always gets it right and are metronome perfect, but the rest doesn't. It's unreasonable to expect perfection, especially on a live take.
I remember a few months back people nitpicking at Steve Harris isolated live track. I'm not a maiden fan, i dont even own a record so theres no bias in defending him, but first of all, guy is playing live so its probably a given the tempo fluctuated, and second, he's in maiden, they're about putting on a show. You're gonna nitpick because the guy can't be 100% perfect while he's walking all over the stage and entertaining a crowd? You're missing the point. If i can only tell someone is making mistakes or being sloppy with an isolated track, then as far as i'm concerned, they played it right.
