Hahaha, I have been hearing ghost vocals to this track in my head as well haha. We'll just have to bring this to karaoke bars and rock some faces
As for the album, I have about 5 tracks off it on my myspace page. Though it makes me feel dirty to post a link to a myspace, any myspace, you might get a kick out of hearing what this album will sound like.

As for technical 70's prog bands, You can almost do no wrong. Almost every 70's prog album had at least a few 7/8 sections, without exception. But some of the more memorable and technical albums I can think of are:
Locanda Delle Fate - 1977 - Forse Le Lucciole Non Si Amano
Cortex - Troupeau Bleu (1975)
Cos - 1976 Viva Boma
Univers Zero - Ceux Du Dehors
Cherry Five - Cherry Five (Later known as the band Goblin)
Goblin - Roller
Arti E Mestieri - Tilt (1974)
UK - Danger Money
UK - UK
Area - Crac
Lotus - Lotus (1974)
Starcastle - (1976) - Starcastle
Starcastle - (1977) - Fountains Of Light
Necromandus - Orexis of Death (1972)
BANCO DEL MUTUO SOCCORSO
The list goes on and on. But definitely, if you enjoy technical music, 70's prog as a wide open source of virtually untapped inspiration. I mean, other than Spiral Architect, and a handful of other bands around, 70's prog is the next most technical music ever crafted.
