A Tongan-American band, 13 Crowns, has released its debut single “Grateful” today September 11.

The band is made up of seven siblings, the eldest of thirteen children of Haini Wolfgramm. Haini performed as a bassist for the iconic 80’s band, The Jets.

"13 Crowns" band members are Eve (21), Heinrich (20), Isabella (18), Tihane (16), Abraham (15),  Maikeli (14) and Nora Wolfgramm (12).

The band stated: “The oldest members were determined to follow in their parents’ footsteps.”

“The journey began in 2006, when their dad purchased instruments and taught them how to play. Plenty of woodshedding, practice and live performances helped them hone their craft..."

The chart performance of “Grateful” will be determined as the week progresses. The song was written by song writer, Jason “Poo Bear” Boyd, who has written hit songs for top artists such as Justin Bieber (“PYD”), Usher (“Caught Up”) and Chris Brown (“I Can Transform Ya”) and has been published on 13 Crown’s official Youtube page.
