The two new tracks arrive after their debut collaborative album, Better Oblivion Community Center, dropped back in January.

"Little Trouble" is a new original single, while "Sleepwalkin' (Daydreamin' Version)" is a re-work of their album track "Sleepwalkin'".

The two new tracks arrive while Bridgers and Oberst are touring as Better Oblivion Community Center. Earlier this month, Bridgers covered Lady Gaga's "Shallow" at a BOCC show and absolutely nailed it.

"Little Trouble" and "Sleepwalkin' (Daydreamin' Version)" are both out now. Better Oblivion Community Center play London's O2 Shepherd's Bush Empire on 11 May. Find out more.
