Fresh off the stage, Pentatonix is making its way around the globe touring North America twice and embarking on their first European tour. Having incredible success in the U.S., the a cappella quintet give the impression of a fated group, but prior to their audition and eventual victory on NBC’s The Sing-off, not all the members had met. Pentatonix, the name derived from the “pentatonic” music scale, consists of five members Scott Hoying (lead singer), Kirstie Maldonado (lead), Mitch Grassi (lead), Avi Kaplan (vocal bass), and Kevin “K.O.” Olusola (beat boxer). The group originated with the three lead singers who won acclaim from their YouTube videos of pop covers, like Lady Gaga’s “Telephone,” but feeling like they needed an additional “depth” to their sound, they decided to recruit additional members. Firstly they find Avi who was already an admired vocal bass from Southern California, and find Kevin through the magic of YouTube after watching a video of K.O. beatboxing while playing the cello. The group’s relationship cultivates throughout the show playing on their fortes and working through their flaws as a group that seems more mature than it really is. It just goes to show that some people do just “click.”Rarely shying away from experimentation, the quintet performs an array of musical genres from jazz to electronica to indie …etc. The new group has already captured the ears of millions through their live shows, tours, and their popular YouTube channel that boasts over 155 million views and 1.8 million subscribers. Their cover of “Radioactive” (Imagine Dragons) with violinist, Lindsey Stirling, receives universal positive critique deeming it the “Best Response Video”; although not completely a capella, we do see a glimpse of K.O.’s impeccable cello playing. The surge of exposure has led them to put out two albums: PTX: Vol. I and PTXmas. Their newest album PTX: Vol. II is forthcoming.Source: ptxofficial.com
