Opportunity knocks

I don't see why you would not go.
There is no point in not going. I think bandmembers would understand if you would say: "Hey, there is this once in a lifetime oppurtunity for me to travel through Europe while playing music!!"

Dude, seriously, go man.
End of discussion. Fuck bills.
They're only a minor responsabilities, you will regret it for the rest of your life, believe me you will, you will wanna kill yourself later if you don't.
 
Who knows, maybe you meet an even better band in europe who likes your playing and they make 10 times the money, play 10 times the gigs, travel the world. You would pass up an opportunity like this for studio time? That can be done anytime, anywhere, hell you could do you parts in another studio 1200000000 miles away!
