High-mass stars evolve on short time scales giving strong feedback to the ambient interstellar medium in form of ionizing photons, mass loss and kinetic energy before they explode as supernova. With quantitative spectroscopy we can study the different phenomena associated with high-mass stellar evolution. In this talk I will present long-slit and integral-field spectra of high-mass stars in the Milky Way and the Large Magellanic Cloud taken with LBT-Lucifer I and VLT-Sinfoni. In combination with appropriate models their fundamental stellar parameters  could be derived, mass-loss scenarios studied and the evolutionary status of the stars evaluated. These studies help to understand the mass-loss mechanisms during different phases of stellar
evolution and to get a handle on the properties of the host population of these stars.
