Anyone who still doubts that radio is a far more evocative medium that television should listen to The High Snows of Ladakh.

I listened to Chris Brown's travelogue on my iPod while cycling to work this morning and was immediately transported from drizzly west London to the splendour of the High Himalayas.

Brown spent six months living and travelling with nomadic Kharnak yak herders. His documentary is a world away what we do in daily news, where we parachute in large teams with hundreds of kilos of gear and try to get them on air as quickly as possible.

It's one man on a yak with a minidisc recorder -- and that's not something you get to hear very often.
