I stumbeled onto Wolfmother on Myspace and kinda dig them. I don't know if they were mentioned here before? They sound like a late 60's hardrock band, very classic hardrock style. Especially the song "Woman" is great. Good vocals, strong songwriting. I don't get into this kind of retro-rock bands very quickly, but these Australian guys do a good job in my opinion..
