Rascal Flatts

Rascal Flatts ($77.1 million). It might be down three slots from its No. 7 finish in 2007, but this good-time country trio is becoming a concert juggernaut. This is the group's third consecutive year in the Ultimate Top 10, thanks to $55.8 million on the road, $18.2 million in album sales and $3.1 million digitally in 2008. Average ticket price: $59.47.Luis Sinco / Los Angeles Times
