  The holographic dual of large-Nc super-Yang-Mills coupled to a small number
of flavours of fundamental matter, Nf << Nc, is described by Nf probe D7-branes
in the gravitational background of Nc black D3-branes. This system undergoes a
first order phase transition characterised by the `melting' of the mesons. We
study the high temperature phase in which the D7-branes extend through the
black hole horizon. In this phase, we compute the spectral function for vector,
scalar and pseudoscalar modes on the D7-brane probe. We also compute the
diffusion constant for the flavour currents.
