I'm trying to remove all punctuation and anything inside brackets or parentheses from a string in python. The idea is to somewhat normalize song names to get better results when I query the MusicBrainz WebService.

Sample input: `T.N.T. (live) [nyc]`

Expected output: `T N T`

I can do it in two regexes, but I would like to see if it can be done in just one. I tried the following, which didn't work...

```
>>> re.sub(r'\[.*?\]|\(.*?\)|\W+', ' ', 'T.N.T. (live) [nyc]')
'T N T live nyc '

```

If I split the `\W+` into it's own regex and run it second, I get the expected result, so it seems that `\W+` is eating the braces and parens before the first two options can deal with them.
