Synkronized is the fourth studio album by English funk and acid jazz band Jamiroquai. It was released on 8 June 1999 by Work Group in the United States, and on 14 June 1999 by S2 Records in the United Kingdom. While the group recorded the album, bassist Stuart Zender left Jamiroquai, and Nick Fyffe was hired as a replacement. The album contains funk, acid jazz and disco elements. The album reached number one in the UK Albums Chart and number 28 in the US Billboard 200. The UK version of the album includes the bonus track "Deeper Underground", which was released as a single the previous year and became Jamiroquai's only number-one single in the UK. Album information The album's recording sessions began at Jay Kay's Buckinghamshire home studio, Chillington, in 1998. About 9 tracks were recorded, but the band's bassist, Stuart Zender, left partway through the recording in late 1998. Jay Kay hired a replacement, Nick Fyffe, and the album was re-recorded. The revised album was finished and released within 6 months. Synkronized is the band's last album to feature didgeridoo player Wallis Buchanan. The opening track, "Canned Heat", has "svelte Chic Organisation strings, a percolating bassline and a stomping four-on-the-floor rhythm". The second track, "Planet Home", is a "straight, bass-driven funk" track that has techno influences from "ghostly ambient harmonies to bone-shaking synth bass," and an "out-of-nowhere Latin hustle breakdown". The next track, "Black Capricorn Day", has a "driving funk groove with sassy horn interjections" which tend to "stutte[r] like a record on a turntable", with its lyrics about being depressed. "Falling" is a "bass driven" acid-jazz ballad track, which is followed by "Destitute Illusion", an instrumental track "swamped in layer upon layer of antique analogue synthesizers", and has the "scratching of DJ D-Zire". The seventh track, "Supersonic", has a "didgeridoo and dobro drone against electronic percussion and a squiggling synth bass, all of which builds to an hallucinogenic mid-song samba break." The "breezy" track "Butterfly" has "a wobbly bassline that rises up and swamps the chorus." "Where Do We Go from Here?" was described as the point of change within the group's sound, using rocks with a leap-frogging blues piano and tangy bongos. The final song on the album, "King for a Day", has "dramatic piano and sympathetic strings", with its lyrics referencing Zender's departure.
