Saw this poster taped to a lamppost in my neighborhood last weekend. There is so much to admire about it. My first thought concerned the talent/practice angle as espoused by Anders Ericsson.
I played in a bunch of bands when I was a kid. Although we were generally dreadful, playing clumpy versions of bad cover songs at poorly attended basement gigs, it was hard to deny that all that very deliberate practice paid off.
