The thing that shocked me most about this album was how strong Bruce's voice is. It's been 5 years since the final frontier and I was honestly expecting his voice to decline slightly and thought they would write more melodies in a lower register, but the opposite is true. In my opinion Bruce sounds better on this album than he did on TFF, AMOLAD and DOD and his vocals are probably on par with BNW. The highest note he hit on BNW was a C#5 on TTLBLAH, other than that he hit a load of C5's on the title track, a couple on GOTN and a couple on DoM. On the book of souls he hits a G5 scream on SoL, numerous D5's on TRATB and BoS and a few on EOTC, Plus C5's on SoL, TRATB, EOTC and IESF. I just find it amazing that not only does he have the confidence to write and sing melodies in that register but he can hit them notes very convincingly. He sounds less strained than he does on the previous three albums and sounds as good as he does on The chemical wedding.
