I launched HeadButler.com in 2004 as a cultural concierge site that would recommend the best in books, music and movies. And I do mean "best." Because everything ever published, recorded or filmed is available online, I don't have to do what magazines and most web sites focus on the new releases (you know, the ones you pick up six months later and wonder why you bought them.) On the site, I guide you not only to the truly great stuff out now but also to terrific old books, music and movies you may not know. Over a decade, I've published more than 1,500 reviews. It seemed like a good time to pick the 100 "essentials" that I believe will give you pleasure for decades.
