Yeah, Bruce got specific about Mistheria and his keytar when talking about replicating the dual guitar parts, so I guess that's the approach we should expect -- though he also said the band hadn't played together yet, so they'll still have to see what works and what doesn't.
I was surprised to hear Bruce kind of passing on the idea playing Tyranny Of Souls songs on this tour except for maybe swapping in "Navigate The Seas Of The Sun" sometimes, but he sounded very affirmative about planning for future solo tours, so who knows what will come next. Someday I'd really like to see a "Legacy Of The Bruce" type show where he draws an even spread of songs from across all of his solo albums and B-sides, even if he just did a limited set of dates and recorded a video to sell to people who couldn't attend in person.
