Introucing FilterBubble with the latest single "口笛". Not much is known about the musician we think but we tend to find out more within the single. The musician absolutely delivers something that would really calm you down, and does at night time and early in the day. When we first heard it, it really set the mood for us last night, and then listening to the single in the day simply rejuvinates you like water in the dessert. Listen below for yourself to see what we mean.
