It has been 28 years since he first released his own sound source "YABASUGIRU SKILL" in 1995, and RAPPAGARIYA is undoubtedly a living legend who has built the Japanese HIP HOP scene. For the first time in six years, they will release an album bearing the name "CHALLENGER", which is far from their current position. They made this album with a warning to themselves, ``Even if we are veteran artists of our age, we always need a challenger spirit!'' and on the other hand, with a strong sense of fear that this might be our ``last album.'' The work was like a suicide note, but as Yamada Man says, ``As we progressed with it, we became more confident that we could still do it.'' The guest appearances include Hannya, the Last boss of the HIP HOP world who needs no introduction, R-Shitei, who along with Hannya built an era of HIP HOP in the freestyle dungeon, members of KZ and KBD's Umeda Cipher, and the voice actors of Gian and ONE PIECE's Buggy. Participating artists include Subaru Kimura, who is not only active but also the main MC of TX's "Oha Suta," Spinna B-ILL, who built an era in the Japanese reggae scene, and DJ and producer dj honda, who is active on the world stage. . Super veteran artist RAPPAGARIYA has returned to his roots and has completed an album in which he pours his heart and soul into challenging himself.
