A recent find of mine, Makita Mashiro should appeal to some people on here- she's definitely for fans of 'jazz' Ringo and Maron Hamada (she's actually friends with Hamada IRL, and her songs are written by John Kurosaki- who works with Hamada also). She's relatively new to the scene and is about to release her second single next month.
Check out her MV's below!
For those interested in looking into her further, here is her Medicom Toy artist profile
