《PESTO》 是袁子安YZA与音乐人好友 2WELL 的第四首合作单曲，主打简单直白的律动以及强有力的旋律，在 R&B 采样的伴奏上带来的 Urban Hip-Hop 声音的同时，其中渲染过的钢琴声也赋予了此首歌曲一种复古感。
“2WELL 太忙了，那哥们儿每周就只能来录音小半天，但我们都不能搞到半夜，因为第二天一大早还要上班。结果做出来的这首歌刚好是适合在晚上听的，甚至在词里都能表达出我们当时的状态。反正很开心能完成我俩在高中就想做的事情：在一个房间里共同创作 —— 歌里有很多歌词和旋律部分都一起讨论完成，感觉挺不一样的。“
'PESTO' is an eagerly anticipated single release from the talented 袁子安YZA, featuring his longtime friend and fellow music artist, 2WELL. The track boasts a compelling Urban Hip-Hop sound layered over R&B samples and an enchanting piano arrangement that gives the song a distinct retro vibe. The straightforward rhythm and powerful melody make for an infectious tune that will leave you humming its catchy chorus long after the music has stopped.
Despite their hectic schedules, YZA and 2WELL managed to collaborate on this track, working tirelessly to create a vibe that captures their shared passion for music. With only a half-day off each week, the two friends made the most of their time in the studio, pouring their hearts and souls into the song's lyrics and overall creative direction. As YZA puts it, "We made a bunch of projects remotely before, so this time, it's a brand new experience to work with each other face-to-face." The result is a collaboration that reflects the chemistry and camaraderie of two artists who have been creating music together since high school.
