The Jimi Hendrix Experience produced two effective albums all through 1967, Are You Experienced and Axis: Bold as Love, that innovate both guitar, trio and recording tactics. Spooky Tooth released their second album Spooky Two in March 1969. The album was an important challenging rock milestone. Gram Parsons with The Byrds launched the influential LP Sweetheart of the Rodeo in late 1968, forming the foundation for country rock.
