Please consider adding http://www.rock.com.ar to your whitelist of other databases + allowing links to the artist bio pages from the sidebar.

Background:
rock.com.ar is an independent website about Argentinian (and some Uruguayan) rock music that has been around for 20 years. It has bio listings for thousands of artists from the 1960s until today. Each bio page also contains a discography listing as well as link to official artist resources such as their homepage and Facebook page. Their database is fairly complete and I use it frequently when adding and/or making corrections to Argentinian artists.

Their artist pages have one of two formats:
1- http://www.rock.com.ar/artistas/<artist>
examples:
http://www.rock.com.ar/artistas/andres-calamaro
http://www.rock.com.ar/artistas/soda-stereo

2- http://www.rock.com.ar/bios/<number>/<number>.shtml
examples:
http://www.rock.com.ar/bios/0/168.shtml
http://www.rock.com.ar/bios/11/11752.shtml
