Started in 1989, specialising in obscure and rare recordings from the 1950s to the 1970s. Founder Bob Irwin helped a number of major labels reissue material from their back catalogues, including Sony Music's release of their archival Legacy Records label. Later, his restoration work included early material by the likes of Bob Dylan and the Byrds.

The first Sundazed releases were 1960s recordings which heavily reflected Irwin's personal preference for garage rock and surf music. Later releases included the albums of the Turtles and Jan and Dean. The company recently reissued the complete catalogue of albums by New Orleans funk pioneers the Meters.
