This week is a tasty appetizer for a summer that promises to sizzle with great performances.

It starts today when the Cowboy Junkies play the 20th Century in Oakley at 8 p.m. The band is scheduled to visit WNKU today during the 3 p.m. hour with Gary Keegan.

The Canadians, who wrapped up their four-CDs-in-18-months “Nomad Series” project with the release of “The Wilderness” last month, will play two sets tonight.
