Soft x-ray emission and absorption spectroscopy of the $\text{O}\text{ }K$-edge are employed to investigate electronic structure wurtzite ZnO(0001). A quasiparticle band calculated within $GW$ approximation agrees well with data, most notably energetic location $\text{Zn}\text{ }3d--\text{O}\text{ }2p$ hybridized state anisotropy spectra. Dispersion in is mapped using coherent $\mathbf{k}$-selective part resonant We show that a more extensive mapping bands possible case crystalline such as found ZnO.
