The vast majority of the musicians truckin' on up to Strathallan next weekend are based in the British Isles, but Alabama Shakes are not the only visitors from across the pond.

The Stateside invasion begins on Friday with Philadelphia band The War on Drugs, built around the talents of Adam Granduciel, whose three albums - Wagonwheel Blues, Slave Ambient and Lost In The Dream - have been been accompanied by a growing fanbase. Canada's The Beaches - fronted by sisters Jordan and Kylie Miller on bass and guitar - play the Transmissions stage on Friday, and have been compared to previous T in the Park favourites Haim.

Seasick Steve, a popular staple at many a festival since he was introduced to the British public by Jools Holland on New Year's Eve 2006, released a new home porch-recorded album Sonic Soul Surfer this spring and graces the main stage on Saturday, and the appearance of St Vincent (aka Annie Clark) in the King Tut's Wah Wah Tent will be top of many festivalgoer's "must catch" list. Her acclaimed recent eponymous album followed her collaboration with David Byrne on Love This Giant, which the pair toured to Glasgow Royal Concert Hall.

Also on Saturday Ohio-born and Brooklyn-raised Elle King will be appearing on the T Break stage as an invited guest, following tours with Ed Sheeran and James Bay. The New York Times detected in her a mix of Adele, Joan Jett and Brenda Lee.

Come Sunday, the Alabama Shakes only fellow countrymen are Philadelphia's Modest Mouse, masters of the pithy album title from debut This Is A Long Drive For Someone With Nothing To Think About to 2004's Good News For People Who Love Bad News and 2007's We Were Dead Before The Ship Even Sank.
