When rapper Kanye West announced last April that he was producing a track for 30 Seconds To Mars' album This Is War, it's safe to say it raised a few eyebrows even among the most die-hard of The Echelon.Unfortunately, the jury's still out because West's version of the track Hurricane wasn't completed in time to make it onto the band's third album. However, frontman Jared Leto has told MTV News that this "phenomenal" collaboration will see the light of day very soon."Let's put it this way: It's a collision of two worlds, and I think it's a completely unexpected surprise," Leto told the US TV station. "He's not only on the track, but he's phenomenal on the track... It's one of the strongest things that he's done, in my opinion.""It is a song that's on the darker side of things," he continued. "It's the flipside of Kings and Queens - which has a through line of optimism and hope, and a really strong spirit to it - this song explores a different territory, and his lyrics do the same. His singing is incredible on it, and he's done a lot of really wonderful work, and I think this only adds to his work as a whole. Working with him was an incredible experience."Leto also adds that he hopes West will be available to feature in a video for the track, too."I think that would be an interesting element to add for sure. We'll just have to see."
