jazz overtones. One of the jazzier songs on the record, the moody ballad "Tell Me a Bedtime Story", was later re-worked as a more electronic sounding song for the Quincy Jones album Sounds...and Stuff Like That!! (1978). Hancock became fascinated with electronic musical instruments. Together with the profound influence of Davis's Bitches Brew (1970), this fascination culminated in a series of albums in which electronic instruments were coupled with acoustic instruments. Hancock's first ventures into electronic music started with a sextet comprising Hancock, bassist Buster Williams and drummer Billy Hart, and a trio of horn players: Eddie Henderson (trumpet), Julian Priester (trombone), and multireedist Bennie Maupin. Patrick Gleeson was eventually added to the mix to play and program the synthesizers. The sextet, later a septet with the addition of Gleeson, made three albums under Hancock's name: Mwandishi (1971), Crossings (1972) (both on Warner Bros. Records), and Sextant (1973) (released on Columbia Records); two more, Realization and Inside Out, were recorded under Henderson's name with essentially the same personnel. The music exhibited strong improvisational aspect beyond the confines of jazz mainstream and showed influence from the electronic music of contemporary classical composers. Hancock's three records released in 1971–73 later became known as the "Mwandishi" albums, so-called after a Swahili name Hancock sometimes used during this era ("Mwandishi" is Swahili for "writer"). The first two, including Fat Albert Rotunda were made available on the 2-CD set Mwandishi: the Complete Warner Bros. Recordings, released in 1994. "Hornets" was later revised on the 2001 album Future2Future as "Virtual Hornets". Among the instruments Hancock and Gleeson used were Fender Rhodes piano, ARP Odyssey, ARP 2600, ARP Pro Soloist Synthesizer, a Mellotron and the Moog synthesizer III. From Head Hunters (1973) to Secrets (1976) Hancock formed The Headhunters, keeping only Maupin from the sextet and adding bassist Paul Jackson, percussionist Bill Summers, and drummer Harvey Mason. The album Head Hunters (1973) was a hit, crossing over to pop audiences but criticized within his jazz audience. Stephen Erlewine, in a retrospective summary for AllMusic, said, "Head Hunters still sounds fresh and vital three decades after its initial release, and its genre-bending proved vastly influential on not only jazz, but funk, soul, and hip-hop." Drummer Mason was replaced by Mike Clark, and the band released a second album, Thrust, in 1974.
