All the Dire Straits albums are great - get them all, they have nice remasters out now. (though I actually prefer the original version of Brothers in Arms). Most of Knopfler's solo stuff is great as well. He does a very nice piece on one of the Chieftans' albums, seek it out - well worth it and has performances by Sting, Sinead O'Connor, and others on there too. The fact that the D.S. albums are excellent recordings is just a sweet bonus.
