Hardal is one of the pioneering band within the Turkish rock music scene, melding the sounds of psychedelic rock with Anatolian rock influences. Emerging in the late 1970s, they were part of a wave of musicians who sought to fuse Western musical styles with Turkish lyrics and local melodies, giving voice to the unique cultural blend that characterizes Turkey's music heritage.

Their discography, while not extensive, has left a notable mark on listeners and critics alike. The 1979 release "Nereden Nereye!" is often highlighted for its progressive sound, encapsulating the innovative spirit of that era in Turkish rock. Three decades after their initial success, Hardal's members came together to produce "Yeniden Doğuş," which translates to "Rebirth," marking a revival of their music and legacy. Although they are known for the two distinct releases titled "Nasıl? Ne Zaman?"—one from the height of their popularity and the other from their later period—the band's influence continues to resonate with afficionados of Turkish rock, both old and new. Hardal's contributions have not only enriched Turkey's rock repertoire but also advanced the genre globally through their fusion of local sonorities with universal rock elements.
