After COBE, Smoot took part in another experiment involving a stratospheric balloon, Millimeter Anisotropy eXperiment IMaging Array, which had improved angular resolution compared to COBE, and refined the measurements of the anisotropies of the CMB.
Smoot is credited by Mickey Hart for inspiring the album Mysterium Tremendum, which is based, in part on "sounds" that can be extracted from the background signature of the Big Bang [REF].
