•4 Tagore songs sung by artistes for over five generations have been taken.•Multifractal analysis of the songs carried out for different generation of singers.•The singing style of a singer/generation has been quantified by multifractal width.•The neural response of the evolution is assessed with the help of EEG.•EEG complexity provides information about valence lateralization in different lobes.
