Put simply, Metamorphestra didn't "officially" exist until long after TANTAMOUNT was recorded. At the time that TANTAMOUNT was recorded, the orchestra didn't have an identity, because I ran the previous Kickstarter under my own name and similarly released the album as an album of orchestral arrangements of Nick Proch. In fairness to my players who agreed to record for me for the first album (and weren't agreeing at the time to be a part of a group called "Metamorphestra," since it didn't exist under that name at the time), I've tried to avoid referring to the arrangements posted on YouTube thus far as being recorded by Metamorphestra, because I don't like the idea of retroactively signing up my musicians to be part of a named, identified group they were a part of two years prior without having had their agreement to do so at the time.
A lot of the nice articles written so far about the videos posted have been confused about this, but it's not a big issue. THE SHIP OF THESEUS is simply the debut album under the Metamorphestra name. TANTAMOUNT was recorded with essentially the same group of musicians, but it was only released under my own name.
