DESCRIPTION:\n    I shall discuss about the Clustering Generalized Chaplyg
 in Gas (CGCG) as a possible candidate for dark matter-dark energy unificat
 ion. The vanishing speed of sound ($c_{s}^2 = 0$) for the GCG fluid is obt
 ained by incorporating higher derivative operator in the original K-essenc
 e Lagrangian. The evolution of the density fluctuations in the GCG+Baryon 
 fluid in the linear regime will be discussed. Subsequently the results fro
 m the observational constraints on the model using latest data from SNIa\,
  $H(z)$\, BAO and also from the $f\\sigma_{8}$ measurements will be presen
 ted. The matter power spectra for the allowed parameter values will be sho
 wn to be well behaved without any unphysical features.\n\nhttps://indico.i
