It seems every year i think that the amount of rock bands coming through my city must dimisnh at some point. but it seems that it won't be the case this year either. We have the following groups so far coming to ottawa.
Rush
Genesis
there are a bunch for blues fest as well.
I thought it would be hard to beat last summer/fall's concerts which i went to (The Who and TransSiberian Orchestra) but i was happily wrong. BTW if TSO ever comes to within a 3 hr driving distance GO you will not be dissapointed. Basically they used every kind of stage effect i can think of. And the music is amazing if you like symphonic rock. Tickets are stupid cheap. around $60 for floor seats.
