Linking page in a folder to a parent taxonomy page in a different folder

I have 2 folders, songs and artists. My songs have a tax tag ‘artists’ and every song by an artist is tagged with that. On my artist page I have a page collection with all pages tagged with that artist. My question is, how do i link back to the artist page from the song page? I was thinking something simple like this:

<p><a href="/somebrothers/artists/{{ page.taxonomy.artist }}">Artist Home</a></p>

But that only works if the tax name is the same as the slug of the artist, and it doesn’t work anyway it throws an error.

Thanks!

Ok so this works:

    <a href="/somebrothers/artists/{{ tag }}">{{ tag }}</a>
{% endfor %}

But ONLY if the tag is the same as the artist slug - is there a way to ‘slugify’ a tax tag - currently my tag is ‘Foo Fighters’ - I need that turned into ‘foo-fighters’ and it will work.

Thanks

Yes, use the hyphenize filter
