Query: Massive Stars in Transition   We discuss the various post-main sequence phases of massive stars, focusing
on Wolf-Rayet stars, Luminous Blue Variables, plus connections with other
early-type and late-type supergiants. End states for massive stars are also
investigated, emphasising connections between Supernovae originating from
core-collapse massive stars and Gamma Ray Bursts.
