Being way behind in everything, I've only just noticed The Fiery Maze CD release now. It's on Spotify, and I'm listening as I type.
I presume that the album is sung by Abi Tucker like the show was.
It's a nice collection of songs, but it doesn't help for me that it's sung by someone I'm not familiar with. She has a great bluesy/soulful voice, but to me the whole production sounds a bit 'normal'. I think that Tuker herself is doing a good job, but the arrangements are a bit normal, there are few backing vocals, and the recording itself sounds a bit uninspired. Tucker's voice isn't that clearly recorded and there is little if any variation in how her voice is produced.
It does sound like a quick recording of the songs, perhaps live to an empty room, rather than something specifically produced as an album. It's a pity in a way as I feel the songs and Tuker's performance deserve more. But, I suspect that there isn't really a possibility of a full produced version of this work, and having the songs and performance that we do is much better than having nothing.
