You can use Airport Viewer to watch the chaos that is ORD ground operations. Then combine with the audio from Live ATC. Outbound flights go from Metering (121.67) to outbound ground (121.75) to the tower for their departure runway (126.9, 132.7, or 120.75). Inbounds will eventually end up on inbound ground (121.9) after either a north/south ground and/or a couple of tower frequencies.

Air traffic controllers call that a string of pearls.
