Their second album, that backed the Southern Harmony tour that you saw, is slightly above the rest of their albums IMO.
My second fave is By your Side.
Too bad other original or other long-time members don't take part in this reunion.
Basically, those guys did a tour de force: making new stuff with an old recipe. They saved the 1990s musically in my book.
I still remember the first two tracks in "Lions" as one of the best pair of songs to open an album ever.
