LONDON (AP) — Some of the members of Pentatonix knew as youngsters they wanted to become musicians, while others were adults when they figured it out. Scott Hoying says he knew from the time he was 5 or 6. Mitch Grassi says he was a music nerd in middle school and that’s when he decided he wanted to make music for a living. Avi Kaplan says he was in high school when he saw a college choir and realized he wanted to be like them. Kirstin Maldonado says when she got to college, she realized she’d rather be a starving but happy singer than successful and miserable as anything else. Kevin Olusola had to convince his parents that music was his path in life. He was a pre-med student and they were big on academics, but Olusola says he’s never regretted his decision.
