Amazing performance by Martin High Schools Pentatonix “Mary did you know”

Pentatonix (often abbreviated as PTX) is an a capella group of five vocalists from right here in Arlington, Texas! Their work consists of covers of pre-existing songs and some original material, sometimes in the form of medleys. Their music is defined by their own arrangement style, a strong presence of low bass vocals, and a diverse range of vocal percussions.

Their stunning portrayal of ‘Mary Did You Know’ is guaranteed to get you into the Christmas spirit!
