Their newest full length absolutely fell short of what that band is capable of, mostly due to a poor performance from Cove. But to say their first full length with him was bland is insulting. The song structuring and vocals on that album far surpass anything DGD has done, and it's sold better as well. Saosin has a much wider fan base thanks to that album and everything they did with Anthony before that is untouchable.
It takes more than a flashy guitarist and a ginger singing about bitches to be considered a great band in my eyes.
I myself like almost half of that album well enough. I dont think its a stretch to call a good chunk of that album bland though. Im not trying to discredit Saosin at all, theyve progressed post hardcore and alternative music as we know it. I am a fan in the end and used to call them one of my favorite bands but pretty much all of their fanbase knows that theres been a dip in quality for the longest time with them. Just go to the saoboards and take a look around.
tldr; Saosin is an important band but no one expects them to return in all their former glory. Therefore, the possibility of new material surfacing is arguably irrelevant because of their recent track record.
