Especially Silent Cries and Mighty Echoes and Ocean was a great success musically. Eloy makes a wonderful stream of music. Believe me or better watch the following videos :)
From Silent Cries and Mighty Echos Album
The Sun Song - Live Performance 1977
Poseidon's Creation Part 1
Shadow and Light
And some Eloy guitar tabs for prog rockers who are serious about playing their songs.
You can discover more Eloy at Amazon.
