Kaygisizlar were a very short-lived band that gave birth to one of Turkish pop's most compelling groups, MFÖ, and were also a milestone for the phenomenal Baris Manco. One of the starting points for the subsequent heyday of Anadolu pop, the band was formed in the mid-'60s after being conceptualized by Fuat Güner, but later found its true form in 1966 after Güner met Mazhar Alanson. The band's lineup also included Manco (vocals), Ali Serdar (drums), Mithat Danisan (bass), Ender Arol (drums), Semih Oksay (bass), Fikret Kizilok (guitar), and many others throughout its career.
The band collaborated with Manco in 1967 and released a four-song EP that contained the later Manco hits "Kol Dugmeleri" and "Seher Vakti." Most of the later Kaygisizlar releases resembled the initial one -- the records were equally weighted combinations of English-sung rock & roll songs and Turkish-sung folk songs or Manco compositions, mostly in a rock & roll form but with many more innovative touches here and there. Considering the chaos of the Turkish music industry in those days, it's next to impossible to name the musicians who played on any given single, or even name the bands playing on some of the songs, as many different versions, retakes, and even pirate copies of Manco songs have been published. Some Manco releases don't even have the name of Kaygisizlar on their covers, although the members were credited.
In their brief journey, Kaygisizlar and Baris Manco evolved from straightforward rock & roll to a more Anadolu-driven psychedelia-touched music, but it might be concluded that the bandmembers parted ways before reaching a peak. They released "Trip (To a Fair)," the haunting instrumental "Bogazici," "Kirpiklerin Ok Ok Eyle," "The Flowers of Love," and "Ay Osman," which were all important influences for the next step in the Turkish music scene. Kaygisizlar released "Sasirdim/Son Gece" and "Artik Yeter/Huzun" without Manco, but Güner and Alanson soon departed as well, inaugurating their new project, Mazhar-Füat, which later became MFÖ.
