For sibling musicians William Gao and Olivia Hardy, everything comes back to their familyโs South London living room.
โThere was this coffee table that weโd clear off and use as a stage as kids,โ says Hardy, 19, the younger of the brother-sister duo. โAnd a CD player that was always playing Queen, Billy Joelโฆโ
โThe Beatles, ELO,โ Gao, 21, adds.
โA lot of ABBA as well,โ Hardy nods.
Their storytelling is effortless but exciting โ thoughts and phrases passed between them with an ease that suggests theyโve been partners since, well, birth. โMusic has always been a very, very big part of our lives,โ Gao continues. Hardy agrees: โLooking back, I donโt think I even realized how big it was.โ


As they lounge on CMโs conference room couch โ munching on dried seaweed snacks and Diet Coke โ itโs hard to believe they were performing for a full house just some hours before. Known jointly as Wasia Project (the name a nod to their mixed Chinese British heritage), Hardy and Gao have been making innovative indie-pop music together since 2019. Hardy sings lead vocals and Gao plays the keys, but their sound is a bit harder to define: โWe usually say itโs a mix of classical, jazz and pop, but weโve never really known how to place it,โ Hardy admits. Gao explains:
โWe both gravitate to lots of different types of music, but when we make our own, itโs what weโre making. Itโs ours.โ
This year has been Wasia Projectโs biggest since they began, Gao tells me, fiddling with the fan-made hat draped around his shoulders. (โItโs just so cozy; I havenโt taken it off!โ he beams.) After playing seven sold-out shows across the U.K. in February, they spent the spring supporting singer-songwriter Tom Odell and Grammy winner Laufey on their respective European and U.S. tours. Last night, they played their first headlining show in Los Angeles, selling out the iconic Troubadour to close out four months on the road.
โItโs just a massive privilege,โ Hardy begins; โA real โpinch meโ experience,โ Gao interjects. โThe number of countries weโve been able to travel to and the people weโve connected with in such different places โ itโs just extremely huge,โ Hardy says. โSo huge that you kind of canโt process it and take it in.โ

As the conversation shifts to their upbringing, Wasia Projectโs unique mosaic of influences starts to take clearer shape. Though they grew up dancing in the kitchen to their parentsโ classic rock records, at school, the siblings were classically trained โ Hardy in violin and Gao in piano and voice. โI remember I would have to go to Saturday academies at his school, actually,โ Hardy says, motioning to her brother, โwhere my classmates and I took lessons. And I was always like, โMy Saturdays are being eaten up by this!โ But, looking back, I gained so much from being in that environment.โ
Despite their shared love (and clear talent) for making music, the two didnโt think to collaborate until it โjust kind of happened,โ Gao says. โThere was never a sense of like, โFrom this point onwards, we’re doing [music] professionally,โโ Hardy adds. โIt was an organic thing.โ
Their debut single, a crooning alt-pop tune titled โwhy donโt u love me,โ was written in the same Croydon living room where their younger selves so often performed. โWe were just messing around having fun, but we landed on something that really felt like us and our voice,โ Gao says. โWe put it out to share with mainly our friends and family. … It wasnโt until later that we realized that was the beginning of something big.โ


Five years later, Wasia Project has nine singles, an EP and over 1.2 million monthly Spotify listeners to their name. Itโs been difficult juggling the band with their other responsibilities, Hardy says (hers, until recently, being schooling and Gaoโs being his role in Netflixโs โHeartstopperโ), but Wasia offers them โan unparalleled creative outlet.โ Gao adds:
โSanctuary is a good word. A creative outlet and a sanctuary.โ
After years of Wasia Project existing in the space between A-levels and acting auditions, these past few months have bookmarked a new era for the group, Hardy and Gao agree. โItโs been a year of learning,โ Hardy says โ learning about their music, their identities as performers and how to curate the best possible live experience for themselves and their fans.
โIn songwriting, the song is the song. And you can play the same song a million different ways, but at its core, itโs the same song, you know?โ Gao says. โSo, it was really fun bouncing around ideas and experimenting with our music as we developed the show.โ
Hardy laughs in agreement, remembering when they heard fan-favorite single โPetals on the Moonโ at a vintage store in Toronto earlier this month: โI basically hadnโt listened to our records [since going on tour], and it was so funny because it was just such a different sound to how we perform it live,โ she says. โI always thought that the way we play it is just an extension of the record, but it really has become a thing of its own.โ

After four months of rehearsing, refining and reimagining their songs on the road, everything came to an electric end at last nightโs West Hollywood show. Joined onstage by longtime bandmates Luca Wade on drums and Tom Pacitti on bass โ with a special appearance from saxophonist Rachel Mazer โ Hardy and Gao enchanted audiences with a nostalgic performance of power ballad โRemember When,โ a cheeky new arrangement of titular EP track โhow can i pretend,โ a crowd-silencing rendition of hit โur so prettyโ and more โ captivating fans from first note to final bow. Hardy reflects,
โThese shows have all been little pockets of beauty โ little pieces of belonging โ in each place. It really does feel like the end of a chapter, and we’re just so thankful.โ


So, whatโs next?
โWell,โ Hardy smiles, shooting Gao a knowing look. โWeโre finalizing our new EP, โIsotope,โ which we announced last night. The songs were written about growing up in our mid-to-late teenage years, and it’s made of such core and specific experiences and sonic worlds. Weโre very excited to put it all together โ the EP, the short film weโre making around it and the next tour.โ
Gao responds: โEvery project and every process has been different; everything has varied. But the main thing thatโs remained the same is the energy we have. Weโre the constant, and I hope we continue to be the constant as we move forward.โ
Looks like weโve come a long way from that living room.
