This album is fantastic for those getting into progressive metal. I stumbled upon this gem when going through a forum, where someone recommended it to a Dream Theater fan.The vocalist is amazing. Where most progressive vocalists either embrace operatic vocal styles, like in Dream Theater, Symphony X, or Fates Warning, their vocals take a different approach. They experiment with techno-organic vocals, a gruff, but clean Layne Staley (Alice in Chains) vocals, and a more aggressive, yet power-metal type vocals.The guitars are amazing, pulling a lot of John Petrucci's (Dream Theater, LTE) style with Johan Reinholdz's (Andromeda, Skyfire) over the top sharpness.The rhythm section is also impressive as they dance around odd chord progressions and time signatures with ease. The song Envy for example plows through a progression in 5/8.The concept of going through the Catholic seven deadly sins is also interesting, while the last three tracks use musical and lyrical throwbacks to the previous tracks, rolling it all together.I definately recommend this to the person seeking a new metal sound.
