In every artistic discipline worthy of mention, there is one inevitable factor that always creeps into every discussion: you need to practice! Every hopeful artist knows you've got to spend unlimited hours "in the shed", practicing your chops and paying your dues, right?
A little while ago I shot a great local blues band, which also happen to be good friends and comrades of mine, Daddy's Work Blues Band.They played the Half Note Jazz Club, a fairly large and one of the most well known clubs in Athens, where also several famous international artists have appeared through the years.
One major reason I like watching bands like "Daddy's", is that these guys are the proverbial working class heroes. That means, especially as far as the Blues is concerned, they definitely don't fake it. They live it through and through.
