Eddie Gale's Black Rhythm Happening was, for many years, one of the most obscure and unheard Blue Note albums of the 1960s. More recently, it has been reissued on vinyl and CD, and it is generally regarded as a groundbreaking, if flawed, fusion of soul and free jazz. As you can see, the cover of my copy is in rough shape, but record plays well - I don't think the original owner, who wrote his name across that of Eddie Gale on the front, played it that much.
Before recording his own two albums for Blue Note (Black Rhythm Happening from 1969 followed Gales' Ghetto Music from a year earlier), the trumpeter played with Sun Ra and recorded for Blue Note as sideman on Cecil Taylor and Larry Young LPs. His own records featured a choral group (mostly singing in unison), free jazz horns, and dreamy folkish songs accompanied by guitar - the weakest aspect of these albums. Black Rhythm Happening has the added attraction of some guests, including Elvin Jones on drums and alto saxophonist Jimmy Lyons. Jones is wonderful throughout the album, and Lyons' one solo is a highlight of the record.
The mix of styles in the title track is typical of the album. Here's that track, along with "Mexico Thing," with that great Jimmy Lyons solo.
