I see Dead & Co posted summer 2019 tour dates. I think there's 19 dates.
One thing to put out there since I've yet to see any review of the Dead & Co live CDs: I bough the 3 live dates from Feb 2018 of "Playing in the Sand". Sort of wish I would've just bought 1. While the music (as in instruments) sound good & distinct, the vocals sound like you're sitting in the last row. It's not just Weir's mic as it's the same distant hollow sound on Mayer's vocals as well. Oh well. Now you know. Purchase with caution.
