Grateful Dead Inc. is marking Day of the Dead by doing what it does best nowadays: issuing old live tracks. Starting today, the world's most bootlegged band will be offering one song per day as a free download off its website, www.dead.net. They're billing the campaign as "30 Days of Dead." Of course, you have to create a user name and log in -- this isn't the old days of tape swapping, you freewheelin' hippies! -- but after 30 days of live tracks, the hassle should be worth it. The songs are mostly all soundboard recordings that were picked by chief archivist David Lemieux and have never been (officially) released.
