Active Child - You’re All I See Recommendations

What other artists are out there that can provide an essence of otherworldly evocative falsetto’s so finely entwine and beautifully textured with heavenly harp from valhalla like Active Child?

It can be old age like New Order or more modern contemporary with elements of electronic arrangement, acts in Opera, spoke word composition or embellishments that closely resemble secular geogorian chant.

Any recommendations will do, thank you music listeners!
