Hidden Highways is a musical collaboration between Carol Anne McGowan and Tim V. Smyth.
The duo delivers quiet Americana-inflected folk, combining waltzing acoustic guitars and blended vocal harmonies.

The two started working together in late 2010 and their eponymous four-track EP was released in April 2012 on Out On A Limb Records. The CD features two original compositions and two esoteric covers; Jackson C. Franks' , "Blues Run The Game" and Jeff Alexanders , "Come Wander With Me" which featured in an old "Twilight Zone" episode.

Since then they have toured at home and abroad and shared the stage with The Staves, Lucy Rose and Daniel Martin Moore, amongst others. 2012 also saw them awarded the RTE/RAAP breakthrough bursary for best emerging musical performers in their genre.
The duo are currently in the studio recording their debut album, due for release later in 2013.
