To my understanding, tagging is the simple, one colour, scrawling of one’s assumed name. You devise a short nom de plume, mess about to find the best way to write it, and then scrawl it everywhere you can. This made up name is now your tag. This is the lowest rung on the graffiti ladder, and every spotty little wanna-be in creation will write their stupid tag on any likely surface. Most tags suck arse, even from the point of view of the larger graffiti community.
Tagging like this is not art, in my opinion. Some argue that any form of expression is art, that tagging is a legitimate form of expression, the little man sticking it to the system by forcing it to acknowledge his mark, or some such bullshit. To me, it’s just lame and selfish, make up a name that isn’t yours and write it on someone else’s property = lame. It’s purely a little ego trip for a little mind, with no respect for anyone else, and is only carried out for the consumption of like minded idiots. There’s no message, political or social. Writing “fuck the system” would be more valid, because at least the supposedly oppressive forces could read the fucking thing.
The tagging I see is mostly in texta (with highly modified felt pens, filled with home made ink, intended to be as difficult to remove as possible), or to a lesser extent, spray paint. Waxy crayons are becoming more popular now too. The whole thing with tagging is that you only need a single, easily concealed writing implement, you can do it quickly, and disappear.
From tagging, the letterform obsession escalates through various levels of sophistication. Larger, single colour efforts (easier and faster), then with two or three colours, finally the rainbow gamut spanning efforts. We’re talking paint now, mostly aerosol cans (intermixed for custom colours in some cases), but anything goes, rollers, mops, you name it. The larger and more sophisticated the effort, the greater the risk, the planning, the possible desirability of collaboration, and the greater the kudos from the vandal’s peers.
The speed with which a large piece can be executed is surprising. The fuckers wouldn’t work that fast if you were paying them to paint your house, that’s for sure. As to what they depict, it’s usually just an exercise in letterform, and probably has little meaning outside their narrow community. It doesn’t matter that you or I can’t make heads or tails of it. They often sign their masterpieces with their individual tags, or the name of their crew. Some of this stuff is probably art in it’s own right. It’s still self indulgent wankery though.
The problem as I see it is, without the annoying tagging, you won’t get the higher end artsy stuff. It’s a continuum of practice and perfection, played out for the public’s displeasure on our built environment. If I had to choose, I’d say they can all get fucked. The ones will actual artistic talent would find another outlet anyway, and we don’t need the contributions of the rest of the try hard losers.
