Xtra Happy
I initially passed Adelaide off from the 2019 six since its sound quality is a bit inferior to the others, but granted it was the first it's understandable.
The offering to the Aussie home crowd definitely doesn't disapoint though - 'Real's Not Real' live debut, 'Open Water' with the long drum solo, and Adam Halliwell of Mildlife (go listen to Live From South Channel Island *now* I'm warning you) playing flute on Hot Water and the 30 minute 'Head On / Pill' closing jam makes for a great set.
Favorite track: Open Water (Live in Adelaide '19).
