The Downchild Blues Band - who sometimes record and perform as simply Downchild - is a Canadian blues band, formed out of Toronto blues jams at Grossman's Tavern fronted by Donnie Walsh back in 1969.

As a friend of Dan Aykroyd's, Donnie Walsh contributed two songs to the Blues Brothers' 'Briefcase Full Of Blues' album in 1978.

Walsh estimates that more than 120 musicians have passed through Downchild since its inception and has made 32 cross-Canada tours all by van.
