I hate to vote against Hell Bent For Leather but I have to go with Killers here as I play it more often. The Ides Of March into Wrathchild is a great opening. Murders In The Rue Morgue...my favorite Drifter...great album.
HBFL has a disc full of awesome tracks as well. Green Manalishi, Rock Forever, Delivering The Goods, Evening Star, Before The Dawn and the killer title track.
This was very hard.
