That's true that my country is beautiful
About the festivals, we have a lot of them, list them would be hard, but the biggest ones, in music, are probably the 'Jazz Festival' in Montreux (not only jazz music, Deep Purple wrote 'Smoke On The Water' over there and were there several times, as some other rock bands), Paleo Festival in Nyon (between Lausanne and Geneva), Rock Oz'Arènes (in the roman ruins in Avenches, French part of the country) - this year Motorhead will be there
among others -, for the metal music, I think one of the biggest festival is Metal Fest in Pratteln, near Basel. There will be a 2nd edition of another metal festival in 2012 called 'Long I rock' or something like this. Scorpions was in the 1st edition in 2010. There's also a festival in the Italian part of the country, in Locarno called 'Moon And Stars' (ZZ Top were there in 2010) and in the same city there's the Movie festival.
Except festivals, we have quite a lot of concerts, mostly in the German part for the rock, hard rock or metal music - the public in the French part isn't hard rock, as the Sideburn (a Swiss hard rock band) drummer told me once
