Since COBE/FIRAS we know that the CMB spectrum is extremely close to a perfect blackbody. There are, however, a number of processes in the early Universe that should create spectral distortions at a level that is within reach of present day technology. I will give an overview of recent theoretical and experimental developments, explaining why future measurements of the CMB spectrum will open up an unexplored window to early-universe and particle physics, with possible non-standard surprises but also several guaranteed signals awaiting us. I will also highlight the complementarity of the distortion signals and the CMB anisotropies, illustrating that future distortions measurements will shed new light on different inflation models.
