鲸鱼马戏团为李星宇的个人音乐人项目，音乐风格多元。现场演出形式丰富，有电声加弦乐全乐队编制及键盘弦乐三重奏编制，乐队固定成员均为国内一线职业乐手。 　　透过创作，李星宇希望传达这样的理念：“我永远不会给自己设定框架，我希望大家在我的音乐里找到各自的影子，那些熟知的生活细碎，共同编织起的这个世界。我希望大家听到的，是来自一个真实的人说给自己听、说给每一个人听，与每一个生命所共通的、发自内心的言语。 　　"Whalecircus" is a personal music project by Li Xingyu with a diverse range of musical styles. The live performances are varied, featuring a full band lineup of electric and string instruments, as well as a keyboard string trio, with all members of the band being first-rate professional musicians in China. 　　Through his creative works, Li Xingyu hopes to convey the following idea: "I will never set limits on myself. I hope that everyone can find their own reflections in my music, those familiar and intricate details of life, weaving together to form this world. What I hope people hear is the voice of a real person speaking to themselves and to everyone, with words that come from the heart and are shared by all living beings."
