CAST, S2A, and BBS?

So I don't get it at all. Back in the day when homeless people were living under the bottoms of my liquid sky jeans and DJ DB was my savior, breakbeat science had some good shit in their shop, but I had no idea that now they had a gang load of Surface to Air shirts and Cast shirts available online. I mean this is great, but no dumb and bass references anywhere, just a bunch of gritty t-shirt designs for us losers. Im real confused.
