A power trio is a rock and roll band format having a lineup of guitar, bass and drums, leaving out the second guitar or keyboard that are used in other rock music quartets and quintets to fill out the sound with chords. While one or more band members typically sing, power trios emphasize instrumental performance and overall impact over vocals and lyrics.
The rise of the power trio in the 1960s was made possible in part by developments in amplifier technology that greatly enhanced the volume of the electric guitar and bass. Particularly, the popularization of the electric bass guitar defined the bottom end and filled in the gaps. Since the amplified bass could also now be louder, the rest of the band could also play at higher volumes, without fear of being unable to hear the bass. This allowed a three-person band to have the same sonic impact as a large band but left far more room for improvisation and creativity, unencumbered by the need for detailed arrangements. As with the organ trio, a 1960s-era soul jazz group centered on the amplified Hammond organ, a three-piece group could fill a large bar or club with a big sound for a much lower price than a large rock and roll band. A power trio, at least in its blues rock incarnation, is also generally held to have developed out of Chicago-style blues bands such as Muddy Waters' trio.
Power Trio is a jazz album by pianist John Hicks, bassist Cecil McBee and drummer Elvin Jones recorded in 1990 and released on the Novus label.
The Allmusic review stated "This summit recording by pianist John Hicks, drummer Elvin Jones, and bassist Cecil McBee might not always hit the heights, but it still impresses with a fine repertoire and quality playing... In spite of a few musical missteps and the somewhat tinny sound of Hicks' piano, this fine trio recording still comes highly recommended".
