Cardeilhac was one of the first Swiss progressive
groups. From the looks of their names, they seem to be from the Latin part of the country but the group's name would hint a more Alemanic Swiss origin.
If you can picture The Nice or ELP with a heavy guitar (but not like The Nice's debut with O'List), you might get a good idea of what they sound like (and their drummer is called Balmer.
Cardeilhac remains acceptable for discerning fans to the two afore-mentioned groups.
