The Shake That Brass stages are so good. She had a different vocalist sing Taeyeons part at every stage including a young Wendy. Amber personally went to Taeyeon and asked her if she would feature on the song and Taeyeon couldn't have been happier

Shake That Brass & Beautiful both have all-English versions that were not included in her 1st album because SM was pushing her to cater to the fans that knew her through f(x). They don't have official videos either, but since leaving SM the English versions are what she usually does in her solo concerts. You should be able to find multiple uploads from fans of live stage performermances if you want to hear them.
