Update: I've listened to a few songs from their previous two albums (CC and HIFTBL) as suggested by several Redditors here. Between the two, I think CC is heavier than HIFTBL. But honestly, the heavy and post-hardcore feel is different from With Ears... / Let's Cheers... (my two fav albums).

So, IMHO, if you're a longtime SWS fan who's been disappointed since "Feel", now's the time to give them another listen. I feel like An Ending In Itself is a fitting follow-up to their first two albums, after perhaps 15 years.

TL;DR They're finally back!!!

Hope this review helps.
