Let me introduce you to a YouTube cover artist I discovered around 2008–2009: Alex Goot. The guy’s been steadily covering popular songs on YouTube for years, and his style — clean vocals, simple but well-produced backing tracks — is really easy to listen to. Many of his covers are honestly better than the originals, in my opinion.
I check his channel from time to time to see what he’s covered. He’s worked with artists like Sam Tsui, Tiffany Alvord, Kurt Schneider — that whole YouTube cover community. He has a project called gootmusicon YouTube.
If you like acoustic covers or pop covers in general, give his channel a try. Below I’ll embed a couple of his covers that I personally enjoy. Stay well, peace be with you.
