If you like the early Heads material you would probably like it. It's the three person original lineup, minus Jerry Harrison. Early demos on one disc, then the CBS demos on the 2nd, and the third disc is live stuff from Max's Kansas City in Oct '76 and Syracuse in Jan '77.
The demos sound like demos, but a good representation of where they were before their first album. And the progression from the early ones to the CBS is substantial, too, IMO.
