"Influenced by psychedelia and California rock, pop/rock producer Curt Boettcher (the Association) decided to assemble a studio supergroup who would explore progressive sounds in 1968. Millennium's resultant album would find no commercial success and only half-baked artistic success, but nonetheless retains some period charm. Influenced in roughly equal measures by the Association, the Mamas and the Papas, the SMiLE-era Beach Boys, Nilsson, the Left Banke, and the Fifth Dimension, Boettcher and his friends came up with a hybrid that was at once too unabashedly commercial for underground FM radio and too weird for the AM dial. It would have fit in better on the AM airwaves, though; the almost too-cheerful sunshine harmonies and catchy melodies dominate the suite-like, diverse set of elaborately produced '60s pop/rock tunes." - Richie Unterberger
"This record can truly be described as a bona fide lost classic. The brainchild of producers Curt Boettcher and Gary Usher, the group was formed out of the remnants of their previous studio project, Sagittarius, which was preceded by yet another aggregation, the Ballroom. On The Millennium Begin, hard rock, breezy ballads, and psychedelia all merge into an absolutely air-tight concept album, easily on the level of other, more widely popular albums from the era such as The Notorious Byrd Brothers, which share not only Usher's production skills, but similarities in concept and construction. The songwriting, mostly by Joey Stec and Curt Boettcher, is sterling and innovative, and yet never strays into the area of psychedelic overindulgence which marred so many records from this era. "It's You," for example, by Stec, is as powerful and fully realized as you'll ever hear from the era, easily on par with songs by the Beach Boys and the Byrds, and, yes, even the Beatles. Begin was at the time the most expensive album Columbia ever produced, and it sounds like it. An absolute necessity for any fan of late-'60s psychedelia and a wonderful rediscovery that sounds as vital today as it did the day it was released." - Matthew Greenwald
