The 2013 movie Begin Again starring Keira Knightley and Mark Ruffalo features "Drowning Pool" over the opening credits.

They played SXSW in Austin, Texas, a few days beforehand.  The following year the band travelled to Australia and played their first shows there, opening up for Crowded House on the latter's first reunion gigs.  The Walls opened the shows in Sydney and Melbourne and also performed their own gigs in both of those cities.  The band's third album "Stop the Lights" was released in 2012.  The first single "Bird in a Cage" became a firm favourite with Irish radio, in particular with Irish DJ Tony Fenton who championed them.  The second single was the title track "Stop the Lights", an autobiographical story of a motorbike crash.  A video was shot for the song in the brother's hometown, Ennistymon, and in the Dublin mountains.
