i like your categorys

Yeah, of course you can get crap in all categories but it's still true that a post-xxxx band will be more likely to interest me than an xxxx band.

And so the description has served its purpose. It's not about 'good' or 'bad' - that's about individual quality. If you saw a band night advertising itself as 'Good Bands' that tells you less than nothing.

I wasn't actually having a go at you personally with the book reading thing, it just gets on my tits when people go on about how we shouldn't categorise music. It just misses (a) the way the human brain works naturally and (b) that these categories are there broadly to tell you if a band is the sort you might like.

Hence you categorise and describe things in ways that you hope make sense to other readers. If someone said "there'll be three good bands on tonight" or someone said "there'll be a post-rock band, a kind of post-punk one and a slightly weird rock band with angular guitars", it's not a great description but a sound can't really be described. It still tells me about 10000% more about what's going to be playing than saying there are three good bands.
