Simply put, Chorus of Giants is a masterpiece. No other album I've bought in the last five years or so has been blazing out of my speakers quite as frequently as this one.
The guitars and bass are huge, the compositions are varied, and the drums defy cliched description.
The only thing that lets it down is that, like most modern metal, the sound is rather compressed; with a more dynamic master this could well be my favourite metal album of all time.
Don't hang around, give Thorun your money!
