I called Jim, the Beatles expert, and he said Hamburg was like a sleazy European Las Vegas, complete with prostitutes and seedy bars. Hamburg would pay big money for British bands to come and play, and often bands, incuding the Beatles, would play for eight hours at a time. John Lennon said that there best music was never recorded, referring to these early days on non-stop playing. I assume this is how they got good at playing as well.

Too bad more bands don't put that much playing time into learning their instruments and crafting their sound. Bands like Good
Charlotte either don't care about getting good or aren't encouraged to. Record companies sign up crap that will sell, not necessarily sound fully formed.

As it would happen, similar to the death of practicing has killed music, the death of the independent circuit is what killed Pro-wrestling. The guys just don't get the in-ring experience they used to. That is why Brock Lesner, hailed as the Next Big Thing, landed on his head when jumping off the top rope at wrestlemania. He, like many other of these new generation wrestlers, just don't have the in-ring experience, which is hurting the business.
