Count me among the group that finds I&D his last great prog album. Even though I've gotten both Joseph albums, I don't think I've listened to them more than once each, same with JCTE. They're FINE albums, I'm sure, but something about them just doesn't bring me back. My willingness to spin Neal related works has waned in recent years, as well, unless it's Transatlantic, Flying Colors, or the DMJ trio albums, all of which are groups where he isn't the main or primary composer. I like him in his more collaborative efforts, it seems, so I hope the project with Keaggy and Thompson comes to fruition since that sounds the most intriguing to me.
As for his singer-songwriter stuff, it's very good, but I rarely go back to it. I enjoyed Songs From November, and I've maybe listened to Life & Times a couple of times, but I can't say I'm rushing to pre-order the new one. But his work with Nick and Ross is just top-notch and I love their vocal interplay together.
Over-all, Neal is still one of my favorite all-time composers and musicians, but I'm at the point where I only revisit his stuff if I'm in the mood to marathon stuff in the lead-up to a new major release, and considering Transatlantic is probably done, NMB might not do a fifth album for awhile, and Flying Colors is a big question mark, I don't see any more Neal Morse Marathons coming anytime soon.
