Only two things come to mind...
The band is so remarkable continue to explore music genres and improving your musicianship to give us great originals
No more straight covers...

(like VH’s version of Roy’s “Pretty Woman” or MM’s Earth Band’s redress of The Boss‘s “Blinded by the Light”
Your developing your sound - why go back to playing others
