Roshni (The Light)

Slide Guitar Ragas From Dusk Till Dawn is a studio album by Indian slide guitarist and composer Debashish Bhattacharya. Riverboat Records released the album on CD on March 30, 2015. The recording features Bhattacharya performing a selection of raga-based compositions adapted for his custom-designed slide guitars, including the chaturangui, gandharvi, and anandam.

The album comprises six tracks that explore traditional and contemporary interpretations of North Indian classical music. Track four, titled Roshni (The Light), spans 17 minutes and 42 seconds. Bhattacharya employs layered slide techniques and rhythmic improvisation in the composition, blending elements of dhrupad and khayal vocal styles with instrumental execution. The track exemplifies his approach to extending the expressive range of the slide guitar within the framework of Hindustani classical music.

Production details for the album remain partially undocumented in available sources. Bhattacharya engineered the recordings with minimal accompaniment, emphasizing the solo capabilities of his instruments. Riverboat Records, a subsidiary of World Music Network, distributed the release as part of its catalog focusing on global traditional and fusion music. The album received attention for its technical innovation in adapting Indian classical forms to the slide guitar, though specific reception metrics or chart performance data are not publicly verified.

Debashish Bhattacharya developed his slide guitar techniques under the guidance of his father, Bimalendu Bhattacharya, and later trained in vocal music under the tutelage of Ustad Aashish Khan. His work on Slide Guitar Ragas From Dusk Till Dawn continues his exploration of raga structures through non-traditional instrumentation, a hallmark of his discography since the 1980s. The 2015 release follows earlier albums such as Calcutta Slide-Guitar: Ragas from the First Hour (1995) and Beyond the Ragasphere (2002), further establishing his role in modernizing Indian classical music for global audiences.
