Yeah sure so the first new song they played and the one they played on most nights was described like this by someone who went to a couple of those shows: "New song starts off with a atmospheric short intro with acoustic guitar, then goes into a complex and pretty rapid exchange between heavy tremolo picking reminiscient of black metal mixed with some punk-esque stuff and some short phases of more DSS sounds and also sections that sounds quite Gauze-y with clean guitars. Has a decently short guitar solo. There's no harsh vocals at all in the song. It's roughly three minutes long.
First impression is that they tried to squeeze a little too much stuff into a too short timeframe, but I'm sure it'll grow on me during the tour, the guitarwork is some of the best they've done so far, I like how its more riffing (BM style) than chugging.
Also, I just realized but the fast riffing parts could be compared a bit to the tremolo sections of the kiri to mayu remake, perhaps."
Someone else said about the song: "the new song had some piano according to Japanese netizens (apparently) - and it "felt more like Die's song than Kaoru's"
Then when the first guy saw them again and heard the song again: "The new song is also developing a bit, the drum pattern has gotten slightly more elaborate since the first show. Will be interesting to follow if more will happen."
There was less comments about new song 2 but there were some from the same guy which first he said: "I'll post a more detailed description of the new song as soon as possible, but its chaotic and has a ton of changes, even moreso than the previous new song... From a first impression, I wasn't as impressed by this one."
And someone else added a bit more: "it will be a lot more chaotic and aggressive than the first new song + will showcase Kyo's various vocal characteristics - and some people even compared the build to what was in Sukekiyo's Vandal."
Someone else popped in saying about one of the new songs: "As for the new song, well one of em, a buddy of mine (who's attending the three shows) described it as totally different from Sustain the Untruth. Has a pretty boss solo from Kaoru. And its "midtempo rock with quiet areas." It also has a breakdown as well."
I also managed to find one other person write something about one of the new songs but I had to translate from Japanese so its pretty bad but here it is, "New song that seems to be going into the new released in December has also been unveiled, but it is a good impression to quite a heavy tune utilizing the various expressions of vocal and lead the drum characteristic."
So yeah, take for what you will from some people who went to see them this last tour and heard the new songs. It has me really excited to see these people have to use lots of ways to describe the songs seeing as they probably will be different in some ways to anything else they've written before.
