The Fantastic Legend of Tohno, man.
I know that's not the "official" title of the song but, this sounds much better than The Mystical Tales from Tono. Rolls off the tongue better and sounds better, even if inaccurate.
Outside of that, this song in particular hits me for a reason. Context-wise, it appears the 2nd stage of PCB, before fighting Chen over in Mayohiga. Basically an abandoned village overran by cats and home to the Yakumo family.
I'm not the best narrator to describe tunes, but the way I can describe it's ambience is bittersweet, distant, melancholic and slightly desperate. At least, in it's DirectSound variant (the one I sent).
The song itself is quite fast; 141 BPM. It's fast pace makes the character of the song something akin to fleeting. It's not slow, it's neither something urgent. It's like walking towards somewhere at a fast pace. Plus, it has a similar earworm-like structure to both it's parts: it makes it feel familiar and sweet.
The first half of the song is the part that makes it feels intimate. It's clear with it's piercing, high piano notes. It is simple with the drum channel and the small choir-like Then comes the flute part (first loop 0:43 ~ 0:56), putting distance with the listener with it's long reverb. It prepares the listener to the second part; it acts as the bridge between both parts.
Then comes the second part. It transforms the song into something distant. It's long, the song structure has changed, it's like you're on the verge of coming close to something yet so far of it. It's reminiscing of Mayohiga itself, a lost place. This part of the second half's structure: (first loop, 1:02 ~ 1:10, 1:17 ~ 1:25 and so on), especially hits hard because of how fast it climbs up. It feels desperate, like hoping to find a place of safety and comfort, yet knowing there's nothing in reach. You don't know how long you're going to remain, but you have to keep moving on. Then again, I mention those parts: those parts I noted aren't the only thing I like about The Fantastic Legend of Tohno. Those part are rather the one that gives the power for the song to follow suit.
I think you can tell I'm not a music reviewer nor a narrator. At least, I don't want to throw buzzwords after buzzwords. However, The Fantastic Legend of Tohno strikes that craving for something that's relentless without going in the intense territory of Necrofantasia. The Fantastic Legend of Tohno strikes the melancholy I'm seeking without sacrificing the dynamism you hear in a song like Shanghai Alice of Meiji 17. It strikes both. It is by far one of the few songs that can strike that compromise: something heavy in it's ambience, and something alive and high in it's notes. It's bittersweet.
