What about the following :
1.DREAMSTATE - Beyond the Mirrors ( 1994 ) Excellent US Prog.Power feat. ex-POWER OF OMENS bass player
2.REBELLION ( US ) - 2 E.P.s , 1 demo and 1 full-length ( and the battle begins...) , Excellent US Power Metal ala early QUEENSRYCHE feat. the fantastic voice of Ed Snow. Keyboard player Chist ST.Pierre posted all songs in his youtube channel. This would have been the ultimate 2-CD release !
3.DREEMWICH - Fantastic US Power / Prog. E.P. and 1-2 demos , tons of material live in youtube , also a myspace page. This is also another must-have !
4. OVERTURE - 4 demos + 1 full-length. Another winner ! 4 rare to find demos ( i have most of them... ) in the classic melodic US Power Metal divine style !
5. DAYS OF YORE , the Canadian melodic Speed Metal masters ! After "The Mad God's Wage" , they released 3-4 demos ( i have the three of them ) , some of them can be found in youtube or blogs , and really kick some ass...
I guess some of the above are quite difficult to be reached / located but just in case someone can help , i believe they are trully winners !
