From underground phenomenon to chart-busting heroes in a matter of months - who'd have thought Goldie Lookin Chain would have leapfrogged the dancing kittens into nationwide fame?
Surfacing on the internet and coming out of Newport like a Welsh Wu-Tang with a touch of Viz, attitudes to GLC vary widely from horror to hero worship depending on your sensitivity to their XXX-rated rhymes.
But anyone who lives in south east Wales will recognise the shell-suited dope-smoking layabouts who inhabit the very real world GLC celebrate in all its minutiae and depravity. No dour Stereophonic-style laments about the dreariness of small town life here - GLC revel in it, from discount stores, markets and mobile phones to mothers with pushchairs and "seven seater scum buses".
Calling their major label debut CD Greatest Hits would seem a typical bit of bravado, but it's not entirely unwarranted since the hit singles Guns Don't People Rappers Do and Half Man Half Machine are accompanied by long-loved download faves such as Time To Make A Change.
What lifts GLC above the suspicion of novelty rap is the quality of the tunes - from the beats conjured up by mixmaster Xain to the rhymes from Eggsy and co, expressing their deep love for old skool hip-hop and electro circa 1983, evocatively captured in Roller Disco.
Whether they get five minutes or five years of fame, GLC's Greatest Hits should stand the test of time.
