Yes, I'd like they go back to compose that way too.. In fact they have done that not only in ADToE but also in DT12, which is actually the only album to feature contributions from every member in their whole discography.. But then again, what JR and JP by themselves have done in TA is more than impressive (not to use the pun), and I like it way too much than what they've collectively done in ADToE..
About what you've said, well, that's not exactly what you said before.. One thing is to say JP doesn't envolve JM in the composition process, and another very different that was JP decision to create TA with JR alone, because that would include JLB and MM in the equation.. Anyway, what I'm saying is that JM's poor involvement is his fault and no one else's, at least if you're looking for the main responsible.. Having said that, the man has now much more participation and/or presence than in SC/BC&SL days..
