Keef Hartley:

Not exactly a singles artist - but a well merited drummer with a vision. A gifted man whose apparel mirrored his deep interest in the American Indian: fringed jackets, widebrimmed hats...
Drummed with Artwoods, John Mayall's Bluesbreakers (alongside new guitarist Mick Taylor from The Gods) on albums "Crusade" 1967 and "Diary Of A Band, Vols. 1 & 2" in 1968 - and then founded this: his own outfit.

Featured scotsman Miller Anderson on guitar (Gibson SG + Carlsbro) and fine lead vocals. And quite a few good reed men.

"Just To Cry" (Lowther/Finnegan)/"Leave It 'Til The Morning"(Hewitson/James/Hartley/Thain) DERAM DM 250 (1969)
A-Side: First few seconds make you think of Spencer Davis Group, then a trumpet calls and changes the mood. Lots of trumpet plus oscillating sounds everywhere. Good vocalist - not a "blues voice" (nothing wrong with that!) but a clear, powerful voice. Modern, jazzy, neat.

B-Side: Much more pop! The Beatles meet some jazz blowers. Playful and rocking. Lots of sounds - and a wah-wah guitar. A good single, this! Hartley obviously surrounded himself with players of the highest quality.
