Compared to it's successor, I consider that Four Walls Bending is more in the "Prog/Fusion" genre. For example, the album begins with a killer track "Velvet Eye", that would fit well on a Gilmour led Pink Floyd CD. On this track the great guitar play of Morris Acevedo should be underlined. In style and in sound he somewhat reminds me of Allan Holdsworth. I should emphasize that all the musicians and tracks on Four Walls Bending are excellent.
