The Hour Glass was a band featuring Gregg and Duane Allman, as well as ultimate Marshall Tucker Band producer Paul Hornsby based in Los Angeles in 1967 and 1968. The first album, Hour Glass, was recorded with an emphasis on lead vocalist Gregg Allman's voice with of songs contributed by songwriters running the gamut from Curtis Mayfield and Jackson Browne to Del Shannon and the Goffin-King team.
On their second album, Power of Love, they were given a freer hand in choosing the songs that went onto the album, which gave it a bluesier feel than its predecessor. Gregg Allman also wrote a couple of songs during this period, one of which, "It's Not My Cross to Bear," would turn up later on the Allman Brothers Band's debut album. The Hour Glass' best moments were unquestionably at the long jams they played at the Whisky a Go Go in LA and on their forays up to San Francisco like for this run of shows just before Christmas, 1967.
Liberty Records had no interest in doing a third album, the first two having stiffed, and the band broke up. Gregg stayed in California to fulfill contractual obligations for Liberty while Duane moved to Muscle Shoals where he became the lead session guitarist. He started building a new band concept with two lead guitars and two drummers and had recruited the rest of the band when Gregg left Los Angeles and entered rehearsal on March 26, 1969, as they rehearsed Muddy Waters' "Trouble No More.” Indeed.
