Hammond Organ Sliders & Keys

I find it interesting and ironic how an affordable church organ became an essential instrument for rock bands, particularly once rock music started getting Heavy. To appreciate how a church organ — particularly, the Hammond Organ — became such an indispensable part of a music scene intended to evoke drug experiences, some background might be helpful: Since the classical era, expansive pipe organs had most often found a home in the type of huge stone and brick cathedrals that were built to accommodate their acoustically enormous sounds. The organ was considered so essential to church music that by the late 19th and early 20th Century, even many average-sized churches had invested in smaller pipe organs that could invest some audio grandeur into their sanctuaries.
Unfortunately, many poorer churches, particularly those that met in more humble surroundings, often in urban areas, were not able to have their own organs.
And so it was that in the mid-1930’s the Hammond Organ Co. began making an alternative for churches that could neither house nor afford large pipe organs. These more affordable (and portable) organs became particularly popular in small Black churches. And given the influence of Black gospel music on the emerging Black jazz, soul, and R&B groups of the ’50s and ’60s, it was not surprising that the Hammond Organ became a central part of their instrumentation. Meanwhile, with a few exceptions, most White rock bands of the time were using easy-to-transport “Combo organs.” Despite their popularity, their thin, skating-rink quality sounded fairly cheesy. (For example, listen to “96 Tears.”)
By 1967, however, rock music was getting heavier. The bass and drums were louder, and the guitars were fuzzed and distorted, and some bands took note of the fuller sounding organs their R&B brethren were using, and many rock bands began replacing their tinny-sounding combo organs with the fuller-and-deeper-sounding Hammond Organ, which, when played through a Leslie amplification cabinet with a rotating speaker, gave the organ a heavy whirling sound — a perfect sound for the newly emerging dreamy, slowed-down psychedelic music of the time.
And the sound of a Hammond Organ played through a Leslie’s rotating speakers caught on in a big way, particularly in 1967 when Whiter Shade of Pale by the psychedelic band Procol Harum became a major hit record, in no small part because of the way the band featured its Hammond Organ front and center, playing a quasi-classical counter-theme against the song’s bluesy melody.
Shortly afterwards, many bands interested in being taken seriously ditched their combo organs and invested in Hammond Organs.
The following are four Hammond Organ-centric records from 1967-1968 that I consider essential, including Whiter Shade of Pale (1967), the Procol Harum record I believe initiated the trend; Vanilla Fudge’s acid-tinged version of You Keep Me Hanging On (1967); Hush by Deep Purple (1968); and Chest Fever by Three Dog Night (1968).
