This is an on-board recording of a police cruiser with engine revving and siren wailing. Lots of engine noise and various siren sounds. Recorded with: fostex fr2le, bp4025.
Recorded in the archeological site of palenque while working on the restoration of mayan architecture, this sound would be heard every morning before the site was open to the public (date: summer of 2018).
I recorded several different guitar riffs played on an eastern, egyptian music scale and then multi-tracked the recordings. Polished the rendered audio a bit with reverbs as well.
