I bought it off iTunes. Rocks very hard. It has the production quality of the Gathering. It's a bit more Low-ish than I thought it would be, but you're right, it has the vibe of older Testament albums with their more recent heaviness.
Strongly recommend it.
It's a kick-ass album. Testament has retained the metal at the core of their music throughout the years.
They never "sold out" as some of the bigger 80's thrash acts (even though i know some tries to make The Ritual a "commercial" album), and oddly enough i happen to like borth their earliest efforts (The Legacy, The Order) and their most recent ones (The Gathering, The Formation of Damnation). Demon is also desent, but i never realy heard Low.
What sursprised me a bit was Alex Skolnicks songwriting, in fact, i hold his song F.E.A.R as the gold medalist on the album. A great song - among other great songs.
But what do you mean with slow? I haven't counted BPM but TFOD can hardly be that much slower than TG. Paul bostaph is a fucking god behind the kit.
