I find it ethical to contact bloggers personally more so than emailing the sites. I'm in search of bloggers that blog about indie, rap, underground, hip hop, electronic, alternative, rock, metal, punk, and experimental music. I'm an artist just trying to reach out to as many media outlets as possible to get some feedback from my latest release and grow my fan base.
So if you like or blog about artist like Del Tha Funky Homosapien, M.I.A, King Gordy, Nirvana, Eminem, MF Doom, MSI, or Madlib/Quasimoto I think I could fit in your blog nicely. Please leave comments so I can contact you please.
As far as art goes, I'm apart of a music-art group and I'm looking for sites and blogs that post neat pictures and drawings to help our visual artist gain more fans.
