Siena Root is a Swedish rock band with its roots in late '60s and '70s rock music. The group was founded in Stockholm in the late '90s. Their sound is based on heavy organ, howling guitars, bass riffing and big drums. It is also often enriched with bluesy soulful vocals, various guest musicians and psychedelic vibes. 
The band believes their music has the warm color of Siena, a city in Italy. Because their sound has roots that go deep, they named the band Siena Root.
