Al is fantastic! If anything, sometimes I like his current slightly more "bronze" voice even more than his young voice.
Matt's falsetto is unbelievably pure and sweet, but it can also soar when needed.
The lead vocals parts are assigned perfectly, with Darian handling the "grittier", more "R&B" parts, Gary handling the more humorous parts, etc.
The band, as has been said, is both very tight, in the good way, and very loose, in the good way. The way they are obviously having fun together is really heartwarming. Debbie!

Also heartwarming is seeing (and hearing) a fully packed and quite lively audience!
An astounding H & V immediately followed by the astounding Love You suite is simply the stuff of dreams. Whoever said that Brian "lost it" after the "demise" of SMiLE? Really?
All in all, it's the best imaginable tribute to Brian Wilson, the man who made nearly all this wonderful music, and made all this possible. The GOAT of music.

To give credit where it's due: I reposted the link posted by Jake Altmayer, who recorded the video, in the Endless Harmony board. And I know how it's difficult, and tiresome, make these audience recordings. Thanks Jake!
