The pair will play live at the Polish festival in August.
A new round of acts have been added to the lineup for this year's Tauron Nowa Muzyka, taking place in Katowice from August 21st through 24th.
One of the highlights from the latest announcement is a joint live set from Theo Parrish and Amp Fiddler. As part of the newly reformed Teddy's Get Down five-piece, the pair have already played several dates across the UK, with sets made up live renditions of Parrish's solo material, plus a few covers. With just Parrish and Amp Fiddler on stage, we're not exactly sure what will be offered up, but if the Teddy's Get Down shows are anything to go by, both will be equipped with keyboards while Parish handles vocal duties. Other new names joining the lineup include Actress, Gui Boratto and Pariah.
