Heavey Seas, maker of the Loose Cannon IPA, has a new Black IPA that's really great
I just filled my growler at Whole Foods/Arlington with that. It's good. But, I would not call it a black IPA. Style-wise, I think it drinks more like a porter. There's a lot of nice roasted malt and it's very smooth. But it doesn't have the internets or hop aroma that I'd associate with an IPA. It is tasty.
