Not Mikawa solo, but just listened
MIKATEN Live2 tape. It is Mikawa + Tentenko. Tentenko was member in BIS, that was "alternative idol band" who also did collaboration with Hijokaidan. (Tentenko - "Hokkaido-born underground idol turned indie pop artist, born 27 August 1990. Began her career as a member of the alternative idol group BiS in 2013, then opted to pursue a solo career following that group's dissolution.")
Mikaten "live2" tape has two live shows, both 35 min long. Mikawa seems to do what he usually does. The broken harsh electronics, always quickly moving, never staying still for long time. However, Tentenko brings in lots of musicality. Beats, colorful electronics and such are often giving elements of music to it, but it feels largely improvised, not "song oriented".
Despite sound quality feels like the usual digital mini recorder quality, and it ain't total noise, I find myself enjoying the tape quite a lot! Perhaps it is also due offering so different material compared to a lot of harsh noise that has been open stereos lately!
Nicely packaged tape has transparent full color art on norelco case itself and then transparent slipcase on top of that.
