Listen to Pentatonix, and you’ll be sure that you hear instruments. In fact, it is an a cappella quintet of young singers — four men and one woman — who perform without any accompaniment, and manage to make a remarkable range of sounds in musical styles ranging from pop to electronica to R&B and dubstep.
Pentatonix emerged just over two years ago, when they won the third season of the a cappella reality show “The Sing Off.” They’ve put out three albums thus far and, with 4.5 million YouTube subscribers, are hugely popular. Pentatonix’s super-fun medley of Daft Punk songs has close to 47 million views on YouTube, and their cover of Lorde’s “Royals” more than 23 million. Pentatonix also sings original songs, like the delicate, powerful “Run to You.”
Avi Kaplan, 24, is Pentatonix’s baritone or “vocal bass.” Kaplan has been making music with a cappella groups since high school and was majoring in opera, as well as winning prizes as part of a vocal jazz ensemble, at a California college when he was invited to join the nascent Pentatonix right before “The Sing Off” auditions. He also plays guitar and arranges choral and a cappella music. Kaplan spoke with The Arty Semite from Texas, where the group was getting ready for a college performance, in a warm up to their 28-date sold-out North American concert tour, which began February 5 in Tulsa and will lead into a European tour.
