Saw the Atlanta show the other night. The band was predictably tight. Connor Kennedy is the featured player, and deservedly so. He sings Dirty Work ostensibly as a tribute to David Palmer's original, but the placement in mid-set makes you think it's to give Donald a rest.
The other guys must be acknowledged too. They are outstanding musicians. All sing and play.
I missed the expected horn section and backup singers who have traditionally fleshed out Donald's sometimes wanting live vocals. (No, we don't care that he's not as accurate as in the studio.)
In all, it is an austere tour. No video, no teleprompters (Donald uses notebooks at the electric piano and on a stand when he leaves the piano). Not even in-ear monitors, opting instead for physical monitors on stage. All of which might--mistakenly--make you think "jazz." But it is not a jazz show. It's a predominantly rock show.
Sadly, the mix was muddy, dominated by an overwhelming, indistinct bass. The room, Symphony Hall, was not to blame. I don't think the bass was part of the small PA mix. They'll adjust.
Still, it was Donald, and I'd go again.
