(2020): A massive 17-track project featuring heavy hitters like Yandel and C. Tangana.

Felicilandia is not just a collection of tracks; it is a concept album about toxic relationships and the numbing effects of party culture. Tracks like "100xCiento" and "Problemón" (with Rauw Alejandro) became instant anthems, but the deep cuts—such as "Díganle" and "Llorar y Perdonar"—reveal Diaz’s mastery of melancholic melody. The production, handled largely by legendary collaborators like Tainy, is lush and textured. It moves between the gritty, lo-fi reggaeton of the underground and the polished pop sensibilities of the mainstream.

As of 2025, Alvaro Diaz has hinted that Sayonara is the closing of a chapter. In interviews, he has discussed the pressure of following up two critically acclaimed projects. Will he return to the upbeat reggaeton of Felicilandia ? Or will he dive deeper into the experimental rock and electronic elements of Sayonara ?

(2024): A profound exploration of heartbreak and "letting go," recently nominated for Best Urban Music Album at the Latin Grammys. Inside SAYONARA : A Concept of Closure
