I would like to report that the artist Gabe Klein – find at https://www.allmusic.com/artist/gabe-klein-mn0003296585 – and the artist Gabe Klein-Kuhn – at https://www.allmusic.com/artist/gabe-klein-kuhn-mn0003155048 – are the same person.
It should be fine to merge them into the page of Gabe Klein (https://www.allmusic.com/artist/gabe-klein-mn0003296585), because this is the name he professionally uses, while he is just credited a few times as Klein-Kuhn.
Find some sources of this correction here (official artist website) https://www.gabenklein.com and here (official SoundBetter page) https://soundbetter.com/profiles/82278-gabe-klein, where he uses the main artist name Gabe Klein.
Here you can find that they are the same person (see name variations): https://www.discogs.com/artist/3191876-Gabe-Klein-Kuhn?anv=Gabe+Klein&filter_anv=1 and LinkedIn page https://www.linkedin.com/in/gabriel-klein-kuhn-76253066 where he is credited as Klein-Kuhn.
Moreover, the same happens with Dean Resturn – find at https://www.allmusic.com/artist/dean-resturn-mn0003867907 – who actually is Deam Restum – at https://www.allmusic.com/artist/dean-restum-mn0001824250 (maybe there was a typo).
