They've teased us all year with spot festival dates, but beginning April 17 Coldplay will launch their first proper North American tour in three years when they hit the stage in Edmonton, Alberta to promote their latest, Mylo Xyloto.

With three Grammy nominations under their belt -- two for "Every Teardrop is a Waterfall" and one for "Paradise" -- the band will be on the road from April through August in the U.S. and Canada, currently slated to wrap things up at the Xcel Energy Center in St. Paul, Minnesota on August 11.

Before they pack up their road cases, they will drop the third single from the album, "Charlie Brown," which goes to radio later this month. They will also appear on the first-ever 90-minute episode of the world's longest-running live music TV series, [article id="1670853"]"Austin City Limits"[/article].
 They'll ring in the new year on the program, which will air on PBS station nationwide on December 31 beginning at 11 p.m. "Coldplay New Year's Eve: An Austin City Limits Special" can also be viewed on demand on www.pbs.org starting at 11 p.m. ET that evening.

If you didn't get a chance to catch any of Coldplay's festival appearances earlier this year, singer Chris Martin promises that the new Xyloto songs will fit in with their soaring catalog, but might also feel a bit ... different. "It's definitely a schizophrenic album ... it keeps changing sounds," he told MTV News. "That's why we called it such a strange thing, Mylo Xyloto. Because we felt like so many people have already made up their minds about us, both good and bad, that we can sort of start again from scratch and try and reflect all the music we listen to and we love."

And while you may not see album guest Rihanna hop up on stage with the band during the outing to sing [article id="1671007"]"Princess of China"[/article]
, there's a shot you might see them do their take on her current hit, "We Found Love," which they [article id="1673353"]covered on BBC Radio 1[/article]
 recently.
