If the focus is straight-ahead rock ala Tom Petty I suggest checking out:

Spoon - Girls Can Tell
Chisel - Set You Free
The White Stripes - White Blood Cells

And little more jam oriented:

Built To Spill - Perfect From Now On

And somewhat proggy ala Yes:

Sunny Day Real Estate - The Rising Tide

Lots more suggestions on tap but that ought to keep you occupied for a while
