As the effect of interstellar extinction in the infrared, using bright red sources it is possible to penetrate the inner disc of the Galaxy. Red clump giants and red supergiants are two particularly useful populations to this aim, as they are bright on the NIR and while the former are dynamically relaxed, the latter trace very recent and massive stellar formation. In this talk I show how, using these stars, we can look for the traces of large structures such as the bar of the Milky Way.
