Alkaline Trio - Anything from 'From Here To The Infirmary' or earlier
My Chemical Romance - Suck overall, but 'I Brought You My Bullets, You Brought Me Your Love' is probably the least worst of their shit.
AFI - Anything from 'The Art of Drowning' and older, 'Black Sails In The Sunset' being a perennial fan favorite.
Alexisonfire - the album 'Crisis' (Boiled Frogs, Crisis, and We Are The End being favorite tracks of mine), IMO their best work to date. Good, clean production while stepping up the intensity a notch over 'Watch Out!'
Decent post-hardcore banRAB in the vein of Alexis would probably be:
A Static Lullaby - '...And Don't Forget to Breathe' or S/T
Rosaline - We're All Just Passing Through
Eden Maine - To You The First Star
More Than A Thousand - Trailers Are Always More Exciting Than Movies
These Arms Are Snakes - 'Easter' or 'Oxeneers Or The Lion Sleeps With The Antelope'
He Is Legend - 'I Am Hollywood' or '91025'; I'm still not too keen on their newest release
Kane Hodder - The Pleasure to Remain So Heartless (catchy as all hell imo)
All Else Failed - 'This Never Happened' or 'Good Enough For The Girls We Roll With'; both great albums on the more hardcore side
