IT TAKES a lot to get me travel to London to watch a 30-minute set by a new band a third of my age these days, especially after a sequence of two gigs and two football matches in five days culminating in a late-night drunken celebration after Brighton’s 3-0 demolition of Brighton reserves (aka Chelsea) on Tuesday night.But that’s what I did last Wednesday, determined to see Tai Haf Heb Drigolyn live on stage for the first time. They are the most original, challenging and inspirational musical experience I’ve had in years.
