Victor Schiavon and Leandro Biffe, two friends and musicians, after years of partnering online, come together in a new big project, isolation in a quiet place to create a new album, "Validation", released by the musical alter ego Yun Li.

The great project had not ended with "Validation", and now, for the second time, the duo Victor Schiavon and Leandro Biffe come together a year later, in isolation, to create the album that became known as "Bittersweet Memories", for the musical alter ego Yun Li.

To conclude not only the "Validation Trilogy" project, but also the alter ego Yun Li himself, Victor Schiavon and Leandro Biffe come together for the third consecutive year for the grand finale, which yielded the album "13 Lentes de Um Final Feliz".
