Query: If you buy a Grateful Dead studio album

This is the one to get.And if you want another, then get Workingmans' Dead.But after that - I would recommend exploring the wide open universe of easily live recordings - the professionally released albums like "Without a Net" and the "Dicks Picks" and "From the Vault" series. If you STILL want more - it's out there for you to find ... around some corner where it's been waiting to meet you! ;-P*
