Boston and Seattle are separated by an entire continent, three time zones, two oceans and their devotion to the football teams they sent to Arizona in pursuit of the Vince Lombardi Trophy.

But the two Super Bowl cities have a lot more in common. They're both important port cities and big college towns. They're both centers of high-tech innovation. And they're the place a lot of great musicians and bands have called home over the years.

Think about it: Boston is known for Aerosmith's blues rock, but the Hub also gave the world the Queen of Disco herself, Donna Summer, the New Wave hits of The Cars and alternative rock icons such as The Pixies.

Extreme calls Boston home; so do Godsmack, New Edition, Juliana Hatfield and yes, Marky Mark & The Funky Bunch.

Seattle might be known for the flannel shirts and hard-rock attitude of grunge from the likes of Nirvana, Pearl Jam, Alice In Chains and Soundgarden, but it's also the birthplace of Jimi Hendrix and the place where rappers Macklemore and Ryan Lewis got their start.

And don't forget Sir Mix-A-Lot -- really, who could? -- or Queensryche, Mudhoney, Candlebox and Death Cab For Cutie.

When it comes to Women Who Rock, both cities can be justifiably proud: Seattle, led by Ann and Nancy Wilson of Heart, and Boston, home to the likes of Susan Tedeschi and Letters To Cleo's Kay Hanley.

Which end of Interstate 90 rocks the most? We're going to let your ears be the judge with playlists including some of the best of both cities.
