The second album, from San Francisco Bay-Area veterans Heathen, is seen as one of Thrash Metals most progressive albums and is often compared to Metallicas ...And Justice For All and Megadeths Rust In Peace. The album consists of long songs with loads of different sections, tempo changes and odd time signatures. You could do worse than start with this oft overlooked gem. Interestingly in November/December of 2011 the band took their place with Sepultura, Exodus, Destruction and Mortal Sin on the Thrashfest Classics package that toured Europe.
