How to remove meta from front page?

Love the theme. I would like to remove the title and the meta under it from the front page. I would also like to remove the bar containing the meta from the category page "the artists". I'm not exactly sure how to go about doing this. Can you help me out? The site is riocostillaart.com

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.post_meta {
display: none;
}
.content-bar .post .post_meta {
display: none;
}
