In a new interview with The Break Down With Nath & Johnny, BUSH frontman Gavin Rossdale spoke about his songwriting evolution toward a heavier sound on the band's last three albums.

When asked if it has become progressively easier or if it's a constant challenge to come up with material that is worthy of being released under the BUSH banner, Rossdale said: "A bit of both.

I'm critical of everything.

And then I know when to let go and when to feel that I've written a song." He also praised SLEEP TOKEN and BAD OMENS as bands pushing boundaries in the heavy music scene.

BUSH's current lineup consists of Rossdale, Chris Traynor (guitar), Corey Britz (bass) and Nik Hughes (drums).

The band embarked on a U.S.

tour earlier this month with support from MAMMOTH and JAMES AND THE COLD GUN.
