[Theme: Blaskan] Posts not showing

That doesn’t look like a theme issue, it looks more like your import failed.

The posts show up but the referenced images don’t and get a 404.

For example:

http://sheetmusicarchives.org/2012/08/29/goluses-nicolas/

But the image is 404’ing.

Can you re-import and this time include the media files by checking the “Download and import file attachments” option?
