Neil Finn - he of Crowded House fame and the newest member of Fleetwood Mac - needs no introduction.

After Liam Finn moved to London with his band Betchadupa, they split and he began a solo career, attracting worldwide acclaim with the I’ll Be Lightning album, and touring with Eddie Vedder, The Black Keys and Wilco.

In 2015 - curious to see what would happen - Liam and Neil finally came together onstage, with the set-list split 50/50. Anyone who saw Finn Sr and Jnr on tour - say, their Shepherd’s Bush Empire gig - will recall Liam as a shaggy-haired and effortlessly charismatic warrior in a red jacket, tearing up the stage with a Viking zeal, which his father, sitting at the piano, watched with joyous, elder-lion pride.

“After those live shows, we thought, ‘Well, wouldn’t it be nice to have songs to play that we’ve written together?’” Liam says, simply.

They worked together to create their debut album, sharing writing duties equally. It’s a family affair: the record features Sharon Finn (Neil’s wife and Liam’s mother), Elroy Finn(Liam’s brother), good friend Connan Mockasin, and Fleetwood Mac legend Mick Fleetwood.
