The result of a four-night stand at the Fillmore East running from June 17-20, 1970, At Fillmore is among the finest, and undoubtedly the most controversial live album in Miles' official catalogue. In order to fit Miles' Wednesday-Saturday residency into a double LP package, producer Teo Macero pulled some of the finer moments from each night and stitched them together to form a medley that took up a single side of vinyl. Initially, some listeners derided Macero's efforts on the basis that several tunes were repeated throughout the album, while others bellyached that editing the songs in such a fashion removed the groove that propelled each night's set. More savvy listeners however, heard the album as a brilliant distillation of Miles' live performance and a compelling record of the band's ability to so drastically reinterpret the same material night after night. Aside from the addition of Keith Jarrett on a wah-wah'd combo organ, At Fillmore features the same personnel that produced the live Black Beauty LP only two months previous - yet the two albums are so different that they could have been recorded years apart. Whereas Black Beauty was loose, mean document, ferocious to the point of frightening, At Fillmore is ambient, funky, tightly wound and extremely focused. On Black Beauty, the music was in complete control. Here, the ensemble holds the reins. Listen close. The results are absolutely incredible.
