I could see that if he was actually joining bands, but it seems more like he's just helping out and getting some work in between Rhapsody tours/albums.
I listened to nothing but Angra at work today. I listened to Aqua twice (and Aurora Consurgens twice too because I love it), and I'm beginning to agree with you. It's not what I was hoping for from that album, but having listened to it a while apart from my initial disappointment I definitely can appreciate it a lot more.
