Recently, Big Big Train had a viewing of the upcoming blu-ray release for Merchants Of Light, due sometime early next year. I can't wait for this release, especially since MOL was a STUNNING live album, finally getting the live video will be a treat!
Also, as pointed out in the 2019 Release Date thread, the band have confirmed that their next studio album is due out sometime next May. No word, as far as I know, on the length or themes/concepts used on the album outside of a couple song titles spotted on sheet music during the recording process. Any year there is a BBT album, it's always contender for album of the year for me, but there's a LOT of BIG albums coming out next year (Neal Morse, Dream Theater, and who knows what else at this point), so it'll be an exciting year for new prog over-all!
