This song is not for everyone but I like it because its a live recording with a single instrument using infinity delay FX. (I turned on the loop delay at :09 after the guitar was flat on the floor.)
All the sounds are made with an acoustic bass. The siren sound is from whistling into the sound hole ect. I made the song looking into the sound hole with the guitar on the floor to not make any unwanted (and forever repeated) sounds. :) - the mono vocal on track 2 added afterwards.
