Have you heard of a band called Muse?
A friend at work introduced me to them the other day and I'm hooked. They're from Manchester, England, and they're awesome. He had a copy of their album Absolution on his computer at work, so he stealthily stored it on the LAN while I went to my computer, copied it to my drive, and erased all trace of its existence (the LAN is more or less off limits to non-work-related buffoonery).
Think of Radiohead's The Bends with extra shots of rock, dynamics, and instrumentation. They roll piano, strings, some electronic, and a standard rock band into a tight, cohesive package. The arrangements are there and there is no wasted space. Give 'em a try.
