How to replace pattern in Album tag?

Hi, look, here's my problem:

I have a bunch of songs like this:

SONG NAME: ROSES

ID3 ALBUM:
ROSES (FT. AEROSMITH) - ED SHEERAN: SINGLE

But I'd like to delete the (FT. AEROSMITH) part out of the album ID3 tag, and leave it just like:

ROSES - ED SHEERAN: SINGLE

How could I do this with an automated command or task without having to do it manually? (There's like 500 files with this album id3 configuration)

Please help me, I've tried and tried but I can't seem to get it right.

Thanks in Advance.

General for deleting brackets and there content:
Klammern mit Inhalt raus

Try an action "Replace with regular expression" for ALBUM,
Search string: (.*)
Replace string:
(leave empty)
Please note that you have to add a space somewhere before or after the brackets or you will be left with double blanks. The blanks do not show in this editor, though.
