Discontinutiy - Ruby's In Attica
If Obliteration took you as far into their minds as you could go with words, Ruby's takes you a step further by being an entirely instrumental album. Well, not quite entirely -- the album was called "the vowel sounds" album for a long time before its release because it features voices on several tracks but no words (well, thats not even entirely true but -- you'll find out for yourself). The album features very original ideas not only in songwriting but production.
