Dotti Holmberg was there at the beginning of Sunshine Pop – the notes to Sometimes Happy Times have her and sister Sheri’s voices twining with Sunshine Pop maestro Curt Boettcher at a folk open mic night. They worked together for a few years in The GoldeBriars, drifted apart, and then reconvened to record a clutch of singles in the mid-to-late sixties, all unreleased; that material, plus more, is all here. Holmberg’s voice has a light joyousness to it that’s balanced by a tart melancholy, and Boettcher’s arrangements often have a breathy spareness that belies the rich indulgences of other projects like The Millennium. When Holmberg is surrounded by the backing vocals of Sheri and Allison Buff, as on the lovely “The Essence,” the effect is near to hallucinatory. The very best of these short, deceptively light pop songs have something of dream logic about them, unreeling the ticker tape of the unconscious.
