Definitely. I do sometimes feel a bit sorry for MP though. DT was a strong and secure place to be that requires a ton of time and dedication and MP clearly got burned out on that due to having around 3 side projects at the same time. He never really had a place with as much creative control or as much impact as DT. I think I can forgive him for the occasional leaking of bitterness for that. Having said that, I haven't really listened to some of his side projects like Flying Colors, Transatlantic, Neal Morse Solo/Band, Winery Dogs (BTW, can someone tell me how those acts compare to the DT of the last decade, quality and style wise?).
In my opinion,
most of them are more or less on par with DT of the last decade quality-wise, but the drum mix is much better on all of them than the last 3 DT albums.
Transatlantic is the project I consider truly on par with DT and in terms of style is the most similar. There is just less metal than DT, but they still get quite heavy at times.
The Winery Dogs would be my next favourite. That second album is fire from beginning to end. Style-wise they can still be considered progressive rock but much less experimental. No long instrumental sections here. Think more accessible prog. probably a good starting place for people new to the genre.
Neal Morse band is also awesome and arrangement-wise can be quite similar to Transatlantic, which isn't surprising since both bands share MP and Neal. Still proggy but less so from what I've heard. Although the Long Day/Overture track they just released from the upcoming album 'Similitude of a Dream' sounds absolutely stunning and reminds me of Octavarium so far from a production and arrangement/compositional perspective.
As far as Neal Morse's solo stuff that Mike has played on I can't really discuss coz I've only heard a couple of songs, sorry.
Metal Allegiance is self explanatory once you've heard one song. It's straight up metal. Nothing like DT at all. Still enjoyable at times though if you just want to rock along.
I haven't really delved deep into Flying Colors or Adrenaline Mob but that's mainly because when I tried I didn't really enjoy what I heard, so make of that what you will based on what I've said about the rest.
Quality seems pretty good though and in terms of style Flying Colors is almost soft/mainstream rock whilst Adrenaline Mob is well, more just metal and probably is the least quality of them all from what I've listened to.
