Start by selecting your input data:

gdalbuildvrt saugus-landfill-composite.vrt ../saugus-incinerator-landfill/saugus-incinerator-landfill-geo.tif ../saugus-incinerator-ash-landfill-infrared/saugus-incinerator-ash-landfill-infrared-geo.tif

Then edit the .vrt to swap bands, eliminating some bands and changing "1" for others. This could be done in Ruby. Then run:

gdalwarp saugus-landfill-composite.vrt nrg.tif
