Guessing you're already up to speed on Bob Marley, right? Well, just in case, if you don't have the Wailers' Burnin' or Catch A Fire, do yourself a favor. Two other cornerstone albums are Burning Spear's Marcus Garvey and Culture's Two Sevens Clash. Someone already mentioned Lee Perry's Arkology, which is fine, though personally, I don't always like it when some tracks are repeated to show different "dubs" or mixes. Because reggae has always been more of a singles medium, however, if you're looking to get caught up in an instant, I'd splash on the 4-CD set Tougher Than Tough: The Story of Jamaican Music. It runs from the '60s to early '90s, and is programmed so beautifully that I can remember having different discs from it in my CD carousel for weeks on end. Hope this helps.
