I'm sorry for beating a dead horse, but dependent clauses exist in the UK and the US. I know it's hard not to be stubborn, but please understand that this is NOT a matter of opinion. This is a grammatical rule which I do not like to see broken. The clause before "He's an awesome guitarist" is dependent; you MUST use a comma.
