He's a very decent music journalist. Not sure he looks or writes any more shyte than Charlie Porter used to. Not sure what Petridis writes usually constitutes 'advice' as such - usually a personal musing on likes/dislikes. That is not a recommendation or defence, mind you.
Porter should have been tarred and feathered for his haircut alone. I might be biased against poor Chuck, mind: I want to take a pick axe handle to anyone who's ever had anything with the British GQ. I really, really, fuqing hate it.
