「SIU2的動感來自充滿靈性的原創作品，這證明了前衛與刺激的融合不一定是『即興』的同意詞。」- Ian Patterson, All About Jazz
「聆聽這隊組合的現場演出是有趣的經驗：彷彿置身盡是高速的光波與撞擊的旋律當中。」 – 馬來西亞《星報》
由音樂人伍卓賢發起的SIU2，是香港一隊領導潮流的音樂組合。樂隊以歷史悠久的笙為首，與三弦、古箏、鋼琴、低音結他與爵士鼓等中西樂器爭鳴發聲，演奏風格游走古今卻又跳出三界的自家創作。SIU2是只此一家別無分號的香港當代音樂有機體，也是香港混雜城市文化的聲音再現。
自2008年先後於香港藝術節呈獻《笙得起》及新視野藝術節演出《超越搖滾新國度》，致力在香港的各式空間與觀眾共享音樂，2011年更與康樂及文化事務署合作推出《中西古今音樂百科》，作巡迴演出及工作坊。隨著聲譽鵲起，SIU2也陸續接受邀請，踏足各地舞台，如2011年4月於中國北山世界音樂節演出，以及5月代表中國出席馬來西亞Borneo Jazz Festival，均廣受好評。
SIU2至今已推出兩張專輯。首張專輯《開門》收錄了2008《笙得起》全套節目，並得G.O.D.襄助作唱片封套設計。EP《西樂》則收錄了2010年《笙得起2》演出之全新曲目，部份作品更獲CNNGo.com用於介紹香港節目之配樂。
「SIU2′s dynamic yet soulful composed music offered ample proof that progressive, exciting fusion is not necessarily synonymous with improvisation.」 Ian Patterson, All About Jazz
「Listening to the group performing live is quite an experience; it feels like you’re wrapped up in a fast-paced weave of bright, crashing melodies.」 The Star, Malaysia
Brought into existence by Ng Cheuk-Yin, SIU2 is a trend-setting musical organism born from the soil of Hong Kong. The Sheng, a musical instrument with its roots from ancient China no less than 3 millennia ago, leads the organism’s process of sound-weaving together with the Sanxian, Zheng, piano, bass guitar and drums. The resulting musical tapestry flows seamlessly through the East and West, past and present while melting down borders between genres. SiU2 is a sonic portrayal of the juxtaposition of disparate cultural elements in Hong Kong. It is one-of-a-kind and its sound not something one can hear anywhere else.
Ever since debuting in the 2008 Hong Kong Arts Festival Sheng It Up and booming outdoor for the first time same year in the New Visions Arts Festival, SIU2 has been striving to let its music reach different audiences through a wide range of different spaces, experimenting with possibilities. The envelop was pushed one step further when it began touring around the city in 2011 with its SIU2 My Encyclopedia of Music, a series of educational performances and workshops, in collaboration with the Leisure and Cultural Services Department. As recognition of its unique brand of sound grew, SIU2 began to be invited to stages and platforms outside its hometown, for instances in April 2011 to the Beishan International World Music Festival in China , and in May same year representing China to the Borneo Jazz Festival in Malaysia, all to critical acclaims.
Two albums have been released by SIU2 so far. Debut album Open Door recorded the complete set as performed in the 2008 Hong Kong Arts Festival Sheng It Up, with G.O.D. chiming in with its creative magic in the album cover design. EP Kon．Fusion houses all new repertoire as performed in the concert Sheng It Up2. Music from this second album was chosen by CNNGo.com to be used in its episode featuring Hong Kong, that very city from which SIU2 had its DNA.
