Well, no one's really sure whether they are brother and sister or former husband and wife. Oasis has a few good songs but the rest suck.
Another band you might want to check out: Sratford 4. Go to:
http://www.stratford4.com/music.html
And get some of their songs.
I personally don't like them much but judging by your previously mentioned bands you may.
Also, if you are interested in something a little more adventerous, check out Liars. Go on Kazaa and get Liars - Mr. You're on Fire Mr. Their CD
They Threw Us All in a Trench and Stuck a Monument on Top is one of my favorites. Check out my review here:

Come to think of it, there may be a few more bands you'd like:
The Mooney Suzuki. More straight-up-rock garage kinda thing.
Spoon. Go on Kazaa and get "The Way We Get By" and "All the Pretty Girls Go to the City." They're really good, if a little weird.
