The list is based on albums I found to be personally ground breaking in the sense that they made me change the way I looked at heavy song compositions. Obviously nobody out there is going to have the same exact list, but feel free to share your own in the comments below.

• Mastodon – Blood Mountain
• Meshuggah – I
• Mastodon – Leviathan
• Opeth – Blackwater Park
• Satyricon – Now, Diabolical
• Mayhem – Ordo Ad Chao
• Type O Negative – Dead Again
• Arch Enemy – Doomsday Machine
• Nevermore – Dead Heart In A Dead World
