...hmm, something approaching the sound might be
Steve Roach's "Infinite Shore", on his "The Magnificent Void"
album of fairly loud ambient music:

Some details can be found in NED:

With total V magnitude of 10.7 and mean surface
brightness of muV = 12.9 per square arcminute, this is
indeed one of the top 200 or so brightest galaxies
in the entire sky. Chris Luginbuhl saw some curious
structure in it with a 12-inch Cassegrainian back in
the 1970s when we were preparing our observing handbook,
and his description is recorded there. It seemed the
position-angle of the isophotes twisted as one goes from
the core to the halo regions. Looks like a nice and
smooth SAB(s)0o lenticular in the SDSS images, however.
