Paul there's nothing like the REAL performance LIVE for a client or audience.....CD's/DVDs etc can be doctored in so many ways and really are a hindrance to what you actually sound and look like, not to mention the entire FEEL of your act and what it does to an audience can never be felt or experienced for a client versus seeing you perform live or at least have others who have seen you refer you and their feedback says volumes!! Your name has to be synonymous with immediate GREATNESS when mentioned amonst circles of people........
"oh yeah we saw them at my friends wedding WOW!!! they were awesome"
"hery whos playing there?....are you kidding? they are so dam good!!! "
Paul this is what gets you work..... I hope you catch my drift as its gotten me thru life so far after 45+ years as a Full Time pro Musician....all I can say is go with the flow, be better then the rest, give 110% when you perform EVERY time, play what the audience wants always not what you like, be very flexible, & most of all mix it up.
