Siena Root is a Swedish rock band with its roots in late '60s and '70s rock music. Wishbone Ash, Deep Purple, Mountain and even Black Sabbath come to mind when listening to their music. The group was founded in Stockholm in the late'90s, and their sound is based on heavy organ, howling guitars, bass riffing and big drums. It is also often enriched with bluesy female vocals, various guest musicians and psychedelic desert rock vibes. 2009's Different Realities, arguably their best album, is a great fusion of psychedelic rock and Indian folk music.
