Musicians (preferably singing) for acoustic project

Looking for fellow musicians for an acoustic project beyond the "party" and "cover" scene. There are enough examples that "good" music can also be sold. Nevertheless, I like common, well-known titles. Gladly also a style mix of apparent opposites such as . Eagles, Swing, Country, Latin or Soul.

Look for harmony instrument(s), also ukulele, possibly also percussion. If possible with singing (solo singing should also be possible, I'm not a "singer" myself, but I like to sing and if necessary "a lot"). I'm a fan of harmony singing. "Harmony" in the musical sense and groove are much more important to me than virtuosity.

So if it works duo, great. Otherwise as a trio or more.

Goal: appearances. The trial effort should be kept within reasonable limits. It doesn't matter whether you are a professional or an amateur. But the musical skills should be enough to be able to play a few (pre-arranged) tracks together at the first meeting.
