Editing Power trio (section)

==History==
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 while still being able 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 blues|Chicago-style blues]] bands such as [[Muddy Waters]]' trio.

In addition to technological improvements, another impetus for the rise of the power trio was the virtuosity of guitarists such as [[Eric Clapton]], [[Jimi Hendrix]], and [[Rory Gallagher]], who could essentially cover both the [[rhythm guitar]] and [[lead guitar]] roles in a live performance. In 1964, [[Frank Zappa]] played guitar in a power trio, the Muthers, with Paul Woods on bass and Les Papp on drums.<ref>{{cite book |title=Frank Zappa: The Negative Dialectics of Poodle Play |first1=Ben |last1=Watson |publisher=Quarted Books |year=1994 |isbn=0-7043-7066-2 |page=26 |url=https://books.google.com/books?id=y9T7GwAACAAJ}}</ref> In 1966, the prototypical blues-rock power trio [[Cream (band)|Cream]]<ref>{{cite book |title=Encyclopedia of Recorded Sound |first1=Frank |last1=Hoffmann |publisher=Routledge |year=2004 |isbn=978-1-135-94950-1 |page=505 |url=https://books.google.com/books?id=-FOSAgAAQBAJ}} [https://books.google.com/books?id=-FOSAgAAQBAJ&pg=PA505 Extract of page 505]</ref> was formed, consisting of [[Eric Clapton]] on guitar/vocals, [[Jack Bruce]] on bass/vocals, and [[Ginger Baker]] on drums.
