There are at least four bands and one podcast with this name, one Hungarian indie-rock/powerpop and one Portuguese alternative rock band from Aveiro. The third was based in the UK, playing alternative rock. Last but not least, SuperEgo was a moniker used by Stone Sour for a while, releasing one demo under that name.
These are photos from concerts where Superego played, so they may be of other bands that played the concert as well.
