Cool Silly (Chinese: 傻酷; pinyin: Shǎ kù) was a Taiwanese-American mainstream pop trio consisting of producer/singer Tone (仲維軍) and rapper/actor Leeway(藍立威), and singer/composer Ray Liu (劉軒蓁).

In 2011, because the band decided that Ray Liu's musical style is more suitable on her own, Cool Silly became a duo consisting Tony Chung and Leeway Lan.

The band was well known throughout Taiwan in 2010 with their hit "Fly" (我飛), which was the theme song for the 2010 Taipei International Flora Exposition([2] 2010 臺北國際花卉博覽會).

The resulting tune, “Light Up Your Dreams”, was later distributed as an EP single in Apple Weekly Magazine and promoted on various internet channels.

The band insists that the personality of their music is not only "cool," but at the same time "silly.
