I'm currently on a Chevelle kick. I recently picked up La Gargola, and it's a good album. These guys have been so solid over the years, they're really much better than many of their contemporaries and unlike so many bands of the past decade, have remained stable and focused on their art. Somehow they've maintained their contract with a major label when so many others have gotten the boot as of late and went indie.
Anyhow, I have to recommend them. So many good albums from them. They've very accessible and catchy, but also a very talented and interesting band within the scope of the mainstream.
