Sounds like you'll appreciate Nico's solo career :-)
Nico’s solo work spawned a range of goth music from Siouxsie and the Banshees to Sisters of Mercy. Still heard in acts like Chelsea Wolfe and ADULt. No doubt it’s dour and atonal but it was distinctive.
Yoko Ono's CDs are a guilty pleasure of mine. They're oddly captivating in their awfulness.
