The direct study of star formation in Damped Lyman Alpha systems (DLAs), the reservoirs of the majority of neutral gas at high redshift, has previously been hampered by observational limitations. The installation of MUSE on the VLT has unlocked an integral field view of these systems, allowing for complete spectroscopic surveys and emission line imaging. I will present a survey with MUSE of 6 z~3-4 DLA sightlines, which span a representative range of metallicities and column densities, to explore associated star formation. One sightline in particular shows a DLA associated with a giant Lyman alpha emitting structure (~40kpc) which was missed by previous deep imaging.
