Which is exactly the case here. Gabriels is an Italian keyboard and piano player with a history in classical music and in metal. That combination alone should make a lot of people interested, except of course the die-hard "metal-is-guitars-drums-bass-vocals" fanatics. The whole album seems to be based on synths and enhanced by top level musicians. It's the first part of a trilogy and it's loaded with epic hard rock.
So what can you expect? Well, anything ranging from Toto and Van Halen to Dream Theater, Rhapsody Of Fire and Helloween. You can expect catch vocal lines in perfect power metal tradition. You can get immersed in flashy guitar solos and straight forward rock music. I'm sure you will raise your fist and sing along plenty of times on this album, certainly with the choruses of 'Fist Of Steel' or 'Seven Stars'.
The biography also mentions that Gabriels is working on a classical music inspired metal album, rightfully titled 'Vivaldi Metal Project'. I'm quite curious for that one too, but for now I think I'll just recommend this epic rock opera to all you symphonic rockers out there. Check it out and allow yourself to get emerged in this whirlpool of music and this gloomy, strange world, created by Gabriels. It's definitely worth your attention...
