2017 release. The creation of songwriter and guitar/harmonica virtuoso Donnie (Mr. Downchild) Walsh, Downchild has an illustrious and colorful history now spanning five decades. Something I've Done is another stellar entry in a discography with very few equals in terms of both quantity (it is their 18th album) and quality. The history of Downchild would certainly make a fascinating movie, and in fact aspects of the band's story were used in the hit movie The Blues Brothers.
