 IBC enjoyed the vast repertoire of traditional blues of the late 1930s to the late 1950s; by covering many blues standards but always being keen to blend acoustic rural blues with a slight touch of Turkish baglama music's essential ingredients.Also in 1997, IBC turned out to be the main base for some vitalising folk-blues projects like Tuzlu Nehir (Salty River), Mama & Friends and Mardi Gras; on which each of them did perform tracks from masters like Blind Willie Johnson, Blind Blake, Fred McDowell, Mahalia Jackson, Leadbelly, etc...

During the "revival movement of Istanbul Underground" circa 1998-9, the band was a unique and leading voice in Turkish underground music community by addition of Orcun Basturk (vocals, drums, objects, gongs, bells) from Replikas, besides other bands like Baba Zula, Nekropsi and Replikas; but modelling Alexis Korner's Blues Inc. to host various musicians without any hesitation to launch a "completely free line up" motto; as whomever did practice any kind of blues, gospel, Cajun, acoustic, electronica, collective improvisation and Anatolian psychedelic rock were very welcome to the line up within Turkish boundaries; until their "farewell tour" in May 2000, just after releasing their second album "Sair Zamanlar (Other Times)" on 7 January 1999 by Doublemoon Records.During 1997 - 2000; IBC line ups recruited numerous musicians, who'd later rule Turkish jazz, Latin, punk, blues, post rock or pop rock arenas, nationally or internationally; circa 2000 and 2010.
