In the “Showa 30s'”, the television age begun.

For the first time TV began to have greater influence than movies and radio. The traditional entertainment of the time (theater and concerts) were supplied mainly to particular people in limited locations. However, the broadcast era – through the mass media of television – was able to reach and influence a broad range of people all across the country. The most appealing form of entertainment – in terms of universal content – has always been “Comedy”.

“Crazy Cats” first appeared in the early television era. They are, perhaps, best known for Jazz music. However, they built an impregnable reputation in the “Comedy” genre through a variety of social satire and jokes.

In the “Heisei” era, the creation of music and film through the computer began. This breakthrough led to a focus on the synthesizer (electronic instrument) as a main stay within the music field.

Meanwhile, speech synthesis technology (Vocaloid) was developed by the Yamaha Corporation. About five years ago I asked Yamaha’s technical team if it was possible to use vocal synthesis to recreate “Ueki” – who was a key member of the Crazy Cats. While it was neither confirmed or denied at the time, the production of Ueki’s vocal synthesis began in 2006.

Normally speech synthesis is not possible if the person is no longer alive, however, in this case we have succeeded in recreating Ueki’s voice. We revived the necessary voice data by analyzing data from multi-track chatter and singing, and ultimately by computing the technology conversion function. Now, it’s possible to create a song with Ueki’s vocal properties ( – as if he was still alive. the sound is exactly as if he was singing himself).

We would like to advocate the creation of new music, but with respect and consideration for the artist – Ueki – who led the rapid growth of the Showa era – and inspired all Japanese people.
