Hi Ozzy
Actually this (hopefully if I can get tickets) will be my first concert ever at the Barclays Center, so I really don't know too much about the place. Don't know about parking, but the LIRR Brooklyn train evidently stops right across the street from the venue, so if you're coming from Jersey & can get to Penn Station in NYC, you can take a train to Jamaica & switch to the Brooklyn train. I'm from Long Island, so I will be coming from the other way.
I hear the tickets will be going on sale this coming Friday Nov 22 at 10am, haven't heard anything about any kind of presale.
I am becoming a big Sabbath fan, never knew much about them until about 2 years ago when a friend made me a couple of compilation cds & I liked them so much that I've been buying the albums now. 13 is amazing- absolutely love it!
Good luck on getting tix!
