On March 17, 1970 The Grateful Dead performed in Buffalo with the Buffalo Philharmonic Orchestra at Kleinhans Music Hall.
"It was a very different one-of-a-kind show in the Dead's history," said Kate Jenkins of the Buffalo Philharmonic Orchestra. 
Mixing a rock band with an orchestra almost never happened some 47 years ago, but Music Director at the time, Lukas Foss decided to take a chance on the Dead. This concert though may as well be dead to Grateful Dead fans. While there's a tape of almost all Dead performances, this one, from Buffalo went undocumented. 
"Even though almost every single Grateful Dead show in history has some kind of tape, this one is like the great white whale, nobody has seen it, and everybody wants to," said Grateful Dead fan Michael Caputo.
Caputo is offering a $500.00 reward for anyone who can come up with the mysterious, and possible nonexistent recording of this concert. Other organizations and people have matched his offer, and now the reward is up to $1,200.
"The idea that the most legendary lost tape of a Grateful Dead show is a Buffalo show, it's something that I think is pretty remarkable."
Caputo says he's been in contact with someone who says they may have a tape, but it's buried in a storage box. The BPO says it would have to authenticate anything that surfaces.
