Yohei Nishi, a member of the four-piece pop band "balconny" from Fukuoka, will start his solo career under the name "westman8" in 2025. Using music generation AI, he released three consecutive mini albums in February, which attracted attention.

And his latest work is his first concept album, "the Strange World (the Pops vol.3)".

All of them are representative songs that have received high praise from the YouTube channel "Balcony TV", and this work can be said to be the culmination of the first half of 2025.
A new era of J-pop born from the fusion of human sensibility and AI. This album is a must-listen, a game changer for a scene that has been stagnant for a long time.
