Help Us Spread The Message by Mighty Ryeders, released on Sun Glo Records in 1978.
"The Mighty Ryeders' 'Help Us Spread The Message' is one of the ultimate rare groove albums.
The details of the album are still shrouded in mystery, but the songs are so great that the signature tune "Evil Vibrations" was sampled on De La Soul's "A Roller Skating Jam Named "Saturdays"- an undeniable masterpiece that has been loved over time!
The other songs are great too, such as 'The Mighty Riders' (A1) with its sharp cutting guitars and bottom-heavy bass groove, 'Let There Be Peace' (A2) with its exquisite interplay of horns and clavinet and the title number 'Help Us Spread The Message' (A5), with its folky sound and peaceful message that gradually builds from a slower tempo, is a superb funk tune. The band's quality is also unmistakably on fire throughout."
