To my surprise Australia's Teramaze history dates to the early Nineties. From the beginning the band has fit the larger category of progressive metal, with a more narrow pursuit of more technical speed or thrash metal. Much of this remains on their third release, the first longer player in 14 years, Anhedonia. Give them credit for surviving.
Generally, Anhedonia is a heavy and speedy album with, sometimes, a coarseness found in modern metal. Often the quick-paced material is marked by staccato drumming and a ton of chopping riffage. The vocal arrangements are equally massive, intricate at times, and generally melodic, but sometimes Brett Rerekura gets into screamo mode.
While I'm not completely convinced or overwhelmed by Anhedonia being that novel or groundbreaking, it's still an interesting work. There are some songs that are quite engaging, even epic, in scope that make this a powerful album. The best are Acts of Reparation, Where the Dead Grow, and Proverb Le Jame. Generally, the other songs are simply heavy and grueling, Egostatic or Machine, by example.
Nevertheless, I think Teramaze accomplishes their purpose. Anhedonia is a dynamic, generally technical, album of progressive speed and thrash metal. Check it out.
