Jamie Lono took on Jamar Rogers on tonight's episode of 'The Voice,' and it was a battle for the ages. While we didn't see any blood, we did see sweat and tears -- and a big vein. Say what?!Coach Cee Lo Green chose Foreigner's 'I Want to Know What Love Is' for the power vocalists' duel.

Both singers started off softly, then grew in volume and strength as the song went on. It was a toned down version of the classic rock hit. It seemed like Lono had more verses to actually sing, while Rogers appeared to emote a bit more -- and Cee Lo pointed out that this song is more about emotion than technicalities. It was a foreshadowing of the final outcome.

"Jamar, you owned it. You owned that whole stage," Adam Levine gushed. "You are ridiculously good. You're gonna go real far."

"I love your vibe," Blake Shelton said to Lono. "I've never seen anything like that before."

Christina Aguilera was complimentary to both singers, but clearly had a favorite. "You don't need to make sandwiches anymore," she told Lono. "Jamar, that very last note that you hit -- you have something all great singers have. That singer's vein! It was popping out. I'm going to go with Jamar."

Cee Lo lamented on Lono's apparent and visible nerves, which appeared to have gotten the best of him during his still-solid performance. At the end of the day, Rogers' redemptive background as well as his vocal prowess gave him the edge over his red-spectacled opponent.

"Jamar, your story is a story of redemption," Cee Lo said. "You display a power and a confidence. Today's winner of the battle is Jamar."
