Virtual singer KAF collaborates with Shinichi Osawa (MONDO GROSSO) for the 14th song in the ‘Suite’ series.

‘Suite’ is a series of collaborations between virtual singer KAF and real-life artists and composers. For the 14th entry in the series, KAF’s collaborator is MONDO GROSSO, the solo project of Japanese artist Shinichi Osawa.

Osawa is a musician, composer, DJ and producer who has worked with numerous domestic and global artists as a producer and remixer, producing music for commercials, installations and soundtracks and a music bar focused on vinyl records.

Osawa has continually electrified the music scene with his many masterpieces and varied collaborations, such as his hit song ‘Labyrinth’ featuring vocals by Hikari Mitsushima.

At the same time, KAF has ceaselessly sent messages from the virtual world to the real one through her unique voice, making this ‘Suite’ collaboration an exceptional encounter.

The title of the song is ‘My Voice’. It was written by Osawa, reflecting on the heavy weight of choosing to live in the service of sound in a world where nothing can be taken for granted.

The story expresses the feelings felt by KAF as she crashes through her teenage years with the help of music. The song was released on download and streaming services on Wednesday, September 6.

Artist comments

Shinichi Osawa (MONDO GROSSO)

There have been times up until now when I have projected very personal feelings into my music. This song is one of them. It may be my first time creating music with someone I haven’t met, even though they exist.

However, I think this is a piece of music that could only have been created under these conditions. I was entrusted with the lyrics and the sound production, and I’m proud that ‘My Voice’ is such a satisfactory track.


Mixed feelings. On the one hand, I feel like this song has brought me out of myself, but even as time passes, there are feelings of drifting somewhere, sometimes within my heart. Whenever I think of it, a part of me feels relief that I feel pain, embarrassment, excitement.

With my voice, I want to recreate the things I could not express in words at the time, the things I didn’t want to say, the emotions I still barely understand. That feeling may be the very origin of my singing, and it has allowed me to sing with my own ‘My Voice.’ I’d like you to listen to it over and over.
