Baltimore....lower level: 85% (watched the final thirty minutes of the first set in the back rows). Mezzanine: 90%. Balcony (where I decided to watch in the upper reaches): 20%. The back fifteen rows had maybe five people.
But....I enjoyed it more than the sold out TA show. Went to the basically sold out DC show in April. I am sure many didn't feel like seeing the same concert again. Sadly, they missed the band in great form, JLB in great voice, and AWE was worth sticking around for.
