There are at least two bands named Ethos: 1) A thrash metal band from Logroño, Spain. 2) A progressive rock band from the US: Here is an excellent example of the US Progressive rock scene of the Seventies: having both technique and excellence, imagination & talent.

Their sound was a little folky at times, poppy at others, even a little jazzy at times, loosely in the shadow of Kansas, Yes, Genesis, early King Crimson and others, with lots of vocals everywhere.
