http://www.jambase.com/ has recently released tour dates for the Grateful Dead's 09' tour! They will begin their tour in North Carolina, and end in good ol' California. Along the way they are scheduled to play in Chicago on cinco de mayo (5/5) at the All State Arena at 7:30p. This will be a summer to remember, with Phish and The Grateful Dead doing reunion tours in the same year. It will most likely be the last year we will have the opportunity to see either of these bands! Tickets go on sale to the public tomorrow morning at 10am! Get your fingers ready, and dont miss out on the most epic concert of the summer!!
