See, I was the opposite. I only checked out Threshold cos I really liked Damian Wilson's vocals in Ayreon, so I was a bit disappointed when I pecked out songs at random only to repeatedly find some other fellow howling along.
Seeing them live clicked everything into place, for me. Instantly fell in love with Mac in the right context. Bought Clone straight off the bat for the Latent Gene alone. This was followed, based purely on the snazzy name, by Psychedelicatessen, which I reacted to in much the same way I reacted to Mac's vocals. "This is fine, but not at all what I was looking for." This is still subject to re-evaluation, as I have yet to see Glynn Morgan live. I liked Under the Sun, though.
Wounded Land didn't come until much later, and despite some superb tracks, superb vocals and a superb cover art, it's never stuck with me in the same way as the albums of Mac's era. So primordial - none of the slick keys, soaring melodies, thick harmonies. Good album, I enjoyed it, but they'd quite clearly not found their identity yet - very different to the band they'd eventually become.
Never checked out Extinct Instinct - only gap in my collection, shame on me! - so I'm very excited to finally hear Damian Wilson singing with the big, beefy, confident Threshold. I do wish it were under less tragic circumstances, but this trailer has cemented that excitement, at the very least.
