One great thing about rock'n' roll is that it allows people to behave in a manner they couldn't get away with otherwise - a freedom that's embraced by local punk-pop trio Hard Candy.
'We couldn't get away with jumping around and screaming on an MTR platform the way we can on stage,' says 20-year-old singer and guitarist Tong Pui-yan.
'We love performing live. It allows us to do things that we can't in everyday life. That's the beauty of music - it gives us the strength and opportunity to abandon the rules.'
Hard Candy aren't your typical band. The all-singing trio are two parts female, one part male - and all energy. Musically, the band can be awkward, brash, off-kilter and oblique, but their on-stage antics make them well worth watching.
The trio - also comprising 22-year-old Renee Ko Wing-tak on drums and 21-year-old bassist Eric Cheung Lok-ming- - have been together for 21/2 years.
'I was originally a bass player and always wanted to write songs, but I never had a chance,' Tong says. 'Eventually, I decided to form my own band.
'My idea was to have an all-girl band. We let Eric join as a temporary bass player, but the arrangement worked really well and all of us felt good about playing together.'
