[Machine Translation] BASSNINJA Mayfly Imazawa produced an album (his 24th in total) with the prime number cicada, the first time in 221 years that 1 trillion of them have occurred in the U.S. In May 2024, he flew to the capital of Illinois, where the 17-year and 13-year cicadas (total 7 types) are said to gather simultaneously, and made an unprecedented collaboration with a swarm of cicadas and recorded their calls on site. The cicadas' calls were recorded onsite. The combination with Imazawa's music will create a unique music for the world and for the future. Recorded May 26-27, 2024 in Springfield and Chicago
