I will try, Saga is a Canadian band who released their first album in 1978, they are progressive rock band but not in the tradition of Rush or Dream Theatre, they are keyboard dominated and the guitar takes a backseat.
Like the Trevor Rabin led Yes, they wrote progressive songs with hooks, and had minor success in the US with the album "World's Apart" that an MTV/rock radio hit "On the Loose" .
The guitar player, multi tracks his guitars and uses influences from blues, to classical, along with the keyboardist who also throws in classical music influences throw out their songs.
ULT on his website No Life til Metal review describes them as "Asia meets Rush with a bit of Genesis thrown in" , it has good as an description I can find.
