After going through a romantic breakup, Kevin Kaarl took refuge in songwriting, shaping the songs that make up this record. The recording took place in an intimate setting, a home studio in Chihuahua, where he worked side-by-side with his brother Bryan Kaarl. Together, they employed digital tools and home-based resources, with Bryan taking on production and mixing, marking his first formal foray into album creation. The sound of Ultra Sodade draws from folk roots but expands by incorporating synthesizers, guitars with processed textures, and dream pop-like atmospheres. The melodies are presented with apparent simplicity, where discreet arrangements cede prominence to lyrical strength. Through its thirteen tracks, the album charts a journey through the different phases of emotional grief, addressing themes such as sadness, detachment, and resignation.
On the track ULTRA SODADE, Kevin's voice intertwines with the collaboration of Monterrey-based artist Nsqk, adding a female voice that repeats the word "sodade," reinforcing the album's conceptual connection. Before the official release, the public could anticipate the album's sound with singles like Esta noche, no me culpes por sentir, and búscame otra vez, each accompanied by music videos directed by Hermann Neudert. Critics recognized Kevin Kaarl's ability to capture longing, highlighting the balance between production and emotional weight. It was described as a reinvention of nostalgia, with notable technical growth compared to previous works, and it was emphasized how the album collects short stories where lyricism, a soft voice, and digital production elements are the central pillars.
