Multi-wavelength observations of supernovae not only probe the explosion mechanism, but also carry information about the configuration of the star at the moment of collapse and the mass-loss history of the progenitor system in the years immediately preceding its death.

In this talk I will discuss several types of new and peculiar astronomical transients and what their properties and intrinsic rates are teaching us about stellar evolution and stellar death.
