After issuing a promising debut album with 2009's 'Black Future,' Tempe, Ariz., quartet Vektor
spent the next year touring with labelmates Exmortus
and headlining their own club dates. We're not sure if it was the road work or plain old maturity, but 'Outer Isolation' takes the band from a purely cult and completest-supported outfit to the top heap of the modern thrash movement. The wildly inspired guitar playing of Erik Nelson and David DiSanto (who also handles vocals) brings to mind the late-'80s work of like-minded progressive thrash groups like Anacrusis
. Vektor love filling their songs up with dizzying arrays of tempo shifts and riff changes, but none of it ever sounds contrived. We wish we could say that about a lot of the other proggy metal records that come across our desk.
