Shinshu Iiyama Nona FestivalSaturday, 7/18, Nagano Prefecture
This is a live event hosted by NONA REEVES. It has been held in Nagano Prefecture, the hometown of drummer Shigeru Komatsu, since 2019. As a pop ‘n’ soul band that pursues a sound with a strong focus on pop music—and is active beyond band activities by publishing a guidebook on ’80s pop and providing songs to other artists—it’s also worth noting which artists they invite. The event, crafted by musicians who are deeply dedicated to sound, is well worth the trip to Nagano.
