Neurosis - Through Silver In Blood (1996)

Artist: Neurosis
Country: US
Genre: Sludge

The single greatest sludge/ambient metal of all time. So heavy and crushing. Definite must for anyone into ambient metal and post-metal.

KEN Mode - Mennonite (2008)

Artist: KEN Mode
Country: Canada
Genre: Sludge/Hardcore

Really sludgy and grooving, but the vocals have a very distinct hardcore sound very similar to Defeater. Another awesome, but overlooked album.
