What are they about? I've heard of the second, but that's it.

Every Monday but 2 episodes of each.

Plot Synopisis:

GURREN LAGANN:
In the distant future, people build their homes and raise domestic animals in subterranean caverns. As a result, they live in fear of the occasional earthquake and cave-in, and have been for hundreds of years. Jeeha is one such village.

One day, a boy named Simon happens to find a small, shiny drill whilst digging to expand the village. At the same time, Kamina, a guy who believes that there is another land above the village, persuades a gangster to break through the ceiling in order to leave the cavern. Suddenly, an earthquake occurs and the ceiling collapses, followed by a big robot breaking through the ceiling.

Kamina is now sure that there is a world above them. Recklessly, he begins to fight against the robot. At that moment, another person appears from the land above. It is a girl by the name of Yoko. With a rifle in hand, she had been tracking the robot. However, all she could do was distract it. Then, Simon shows what he had found to Kamina and Yoko. It's a mysterious robot whose head is also its body.

Now and Then, Here and There:

Shu is catapulted into an alternate reality when he climbs a giant industrial smokestack and strikes up a conversation with an odd-looking girl named Lala Ru. The change happens when sinister forces come to retrieve her. Where is this alternate reality, and why does Hamdo's army want Lala Ru? Shu finds himself smack in the middle of an organization that builds up its army by invading villages, kidnapping young children, and training them. They try to recruit Shu as well, but they underestimate his spirit and his unbelievable ability to not give in to hate. Shu is brash and impulsive, but principled, clearly not what his captors expected.

Watched it for the very first time last night. I really enjoyed it! And I certainly look forward to next week.

Gurenn Lagaan looks awesome...the older brother has a voice actor I know, but i just cant remember what show he's from(I know Simon has yung Sasuke's voice)
Nice show so far B)

If I'm not mistaken Kamina's (I'm guessing that that is the "Older Brother" you are referring to?) Voice Actor is Kyle Hebert he is Teen Gohan and the Announcer in DBZ, Vato Fallman in FMA Ganju and Aizen in Bleach, or to stick to the Naruto list he plays Kiba..
