Changes to the sidebar widget area

Hi there,
You guys must be sick of me by now.

Anyway with the sidebar widget area on this page:

https://polarismusic.co.uk/kin/

and other artist pages on the site, i would like to centrally align the text above the social icons and remove both the large box around the entire widget area and the smaller box around the icons.

Any help would be greatly appreciated.

Thanks
