X4 (“Ten Four”) seeks to combine engaging music, high-caliber performances, and the promotion of quality percussion music by today’s top composers. Comprised of Julie Hill, Ji Hye Jung, Dan Piccolo, and Joshua D. Smith, X4 has performed at various venues across the state of Tennessee, including the Tennessee State Day of Percussion. The name “X4” is a play on words as the call of “10-4” is a sign of affirmation and understanding (incorporating the Roman numeral X for the number 10) and that the group was formed by music professors in the state of Tennessee. While X4 seeks to connect with audiences through a wide range of existing works that are exciting, thought-provoking, and stimulating, they are also involved with commissioning new music, including a recent collaboration with composer Adam Silverman.
