AAAAARGh the dilemma is tearing me apart.

I REALLY LOVE Biffy and The Bronx, and was raring to go to this, very excited and all that.

Then I hear about this XFM Xposure thing at the barfly, with Patrick Wolf, brakes, Danananackroyd, Frank Turner and Dartz!(who i love) and was just about to buy tickets when i saw it was ON THE SAME DAY

:(

what to do?
will the all-dayer finish reasonably early? ie leaving me enough time to get to the astoria for the bronx?
shall i clone myself?
