Unfortunately Javier's solo piece won't be on the album. You'd know that if you've heard the song samples. Here they are: Weightless by Animals As Leaders - Fairshare Music - the home of feelgood downloads
I'm not impressed, at all. Lots of silly djent riffing and guitar solo wankery...none of it is catchy or memorable. It's pretty clear to me that this album won't be as good as the last.
I, myself, am not in favor of most of the distorted riffs and the guitar solo 'wankery', but I do think there are many memorable parts in this album, and that's just judging by the 30-second samples. Imagine throughout the songs in their entirety.
No need to make assumptions yet.
Also, the first one, too, had tons of guitar solo 'wankery' and heavy riffing.
