Bloodstone

American R&B, soul-funk band, formed in 1962 in Kansas City, Missouri.
They started as a doo-wop group: The Sinceres and they moved in late 1960's to Las Vegas, NV.
By 1971 - billing themselves as Bloodstone - they decided to move to Los Angeles, CA, but failed to generate enough interest and they decided to move to London, UK.
They became known for their funk/soul sound that blended Jimi Hendrix-styled rock music with doo-wop and gospel music undertones. Their biggest hit is "Natural High" (1973).
