SYDNEY youngster Brandon Jack has already shown his ability on the football field, but now he has revealed another talent off it – music.

In his spare time between training sessions this pre-season, the 22-year-old has released an original track on Soundcloud.

"Had some spare time over the past week so decided to put this together," Jack wrote.

"Written, recorded and mixed on a Macbook in my one bedroom apartment.

"Hans solo (solo artist) at the moment but looking to turn this into a proper band."

Jack – the younger brother of former Swans co-captain Kieren – is a keen musician, with several of his Instagram posts featuring guitars and one post putting the call out for a drummer to join his band.

Although Jack failed to add to his 27 games and 16 goals for the Swans last season, the speedy forward is contracted until the end of this year.
