"Opiate" is Tool's debut release - a CD made up of the heaviest material Tool had written at the time of recording.  This really comes through on this CD - Although the use of distortion isn't as extreme as "Aenima", the songs themselves are of a far more metal variety. The album opens up with "Sweat", a song with a sudden and loud opening, before being followed by "Hush", a song with lyrics soaked in sarcasm.  "Part of Me" is the third song, boasting both catchy lyrics and chorus.  "Cold and Ugly" and the amazing "Jerk Off" are both live performances which serve to highlight the talents of Tool live - The "Bob-Marley-Wannabe" Manyard talks about is rumoured to be the lead singer of "Green Jelly" jumping around with a dredd-lock wig on.  "Opiate" is the quiet, come-down track on the album. "Opiate" is best seen as a face of Tool - The violent, heavy face wielded like a sledgehammer.  It lacks the subtlety of Tool's later albums but makes up for it in spirit.  The artwork inside the CD sleeve is also excellent and interesting.
