Someone finally mentioned Ceremonial Castings, I thought they were too underground to get mentioned But they're really good depsite having stuff released on a small label that isn't known too well, they even got a review in Metal Maniacs.
They seem like Symphonic Black to me. Something like Ulcus or Stormlord. Some of the vocals seem pretty death influenced, but then again that happens in other black metal bands.
Glad to see Averse Sefira mentioned. Austin has had very few bands worth even mentioning, but they are definitely one and I believe Watchtower is the other.
I saw them with 1349 last Sunday night... I found them to be really boring. I thought that the guitarist was a better growler than the lead growler. Whatever.
Nachtmystium, however, was great. Also worth mentioning: Xasthur, Wolves in the Throne Room.... Wolves in the Throne Room produces music that surpasses beauty.
