Duel continue an impressive streak of heavy releases with Valley Of Shadows.  The band expands upon their retro-tinged heavy metal and up the production with this latest release.  Some of the rough edges have been smoothed out when compared to earlier releases such as the excellent Witchbanger.  Production quality aside, this is still a heavy album with plenty of dirt under it’s nails.  Strike and Disappear may start off with a lighter tone but quickly launches you on a wild metal ride.
