  The dynamical processing of black holes in the dense cores of globular
clusters (GCs), makes them efficient factories for producing binary black holes
(BBHs). Here we explore the population of BBHs that form dynamically in GCs and
may be observable at mHz frequencies or higher with LISA. We use our Monte
Carlo stellar dynamics code, which includes gravitational radiation reaction
effects for all BH encounters. By creating a representative local universe of
GCs, we show that up to dozens of these systems may be resolvable by LISA with
signal-to-noise ratios of at least 5. Approximately one third of these binaries
will have measurable eccentricities ($e > 10^{-3}$) in the LISA band and a
small number ($\lesssim 5$) may evolve from the LISA band to the LIGO band
during the LISA mission.
