With the help of HBO's Louis Wu, we found a few more items to add to our Sheet Music page-- a guitar tab for the solo in Silent Cartographer done by Vicious Circle, XvShadow's guitar tab of the main Halo theme, Marty O'Donnell's own sheet music for Siege of Madrigal from Myth and an extension to Siege done by Robyn "Dephalt" Barbour.
