The debut long-player by the Bee Gees may shock anyone who only remembers them for their mid- to late-'70s disco mega-hits, or their quirky early-'70s romantic balladry. Up until 1966, they'd shown a penchant for melodic songs and rich, high harmonies, in the process becoming Australia's answer to the Everly Brothers. When the brothers arrived in London late in 1966, however, they proved quick studies in absorbing and assimilating progressive pop and rock sounds around them. In one fell swoop, they became competitors to the likes of veteran rock bands such as the Hollies and the Tremeloes, and their debut long-player is more of a rock album than the group usually got credit for generating. Parts of it do sound very much like the Beatles circa Revolver, but there was far more to their sound than that. The three hits off of Bee Gees 1st, "To Love Somebody," "New York Mining Disaster 1941," and "Holiday," were gorgeous but relatively somber, thus giving Bee Gees 1st a melancholy cast, but much of the rest is relatively upbeat psychedelic pop. "In My Own Time" may echo elements of "Dr. Robert" and "Taxman," but it's difficult to dislike a song with such delicious rhythm guitars and a great beat, coupled to the trio's soaring harmonies; "Every Christian Lion Hearted Man Will Show You" was closer in spirit to the Moody Blues of this era, opening with a Gregorian chant backed by a Mellotron, before breaking into a strangely spaced-out, psychedelic main song body. Robin Gibb's lead vocals veered toward the melodramatic and poignant, and the orchestra did dress up some of the songs a little sweetly, yet overall the group presented themselves as a proficient rock ensemble who'd filled their debut album with a full set of solid, refreshingly original songs.
