The truth about Pentatonix is that their music, whether covers or original, remains rather steadily in the pop realm. Kirstin Maldonado’s solo music is also pop music, but a defining reason why she remained in the group while Avi Kaplan left is because his solo music isn’t pop. Rather, as explained by Billboard, Kaplan thoroughly loved folk music before joining the a capella group, and he wanted to return to these roots, which meant leaving the group once and for all. Luckily for him, their countless albums and world tours provided him a large platform from which to bounce off.
Kaplan released his first solo music in 2017 and has continued to release music since. (Interestingly, later in 2017 Kaplan shared a failed relationship with YouTube personality Trisha Paytas, though the former Pentatonix member kept it a secret even though Paytas later revealed it on Twitter.) According to Screen Rant, Kaplan explained in a video surrounded by his bandmates that his leaving was friendly and that he missed his family and friends with all of the hard work that went into being in the group. The video was posted to their Facebook page in May 2017 and his last show was in September of that year.
As explained by Billboard, Kaplan continues to release music. His second EP, “I’ll Get By,” was released in 2020, and his latest single, “First Place I Go,” was released in November 2021. From here, there are only higher goals to be met for a professional like Kaplan.
