Perhaps feeling unjustly tagged as heavy rock fuds after releasing 2004's Blue Cathedral to popular acclaim, Comets on Fire commit the typical heavy rock fud mistake of putting out a "mature" album to show off their musical erudition that sounds nothing like their top-selling prior release. Instead of knocking out another wall-shaking psych rock blast - maybe based on a misreading of a fantasy literature artifact related by the stoned hippie who lives next door - Avatar comes off like a series of sedate recital pieces performed from sheet music while seated in the round. You get just about everything you've never wanted to hear from Comets on Fire, from sensitive ballads to Al di Meola-inspired jazz-rock noodling. The lone suggestion of past glory, Holy Teeth, is kept under three minutes and seems so incongruous, it could've been cut by a different band. Nothing but sad.
