Run and Gun live music

Gear available: Panasonic Lumix G85 Rode VideoMicro Zoom H1

Going to see a favorite band at an outdoors festival and thinking about bringing my new equipment to test it out. The Rode mic would be attached to the h1 (setting levels accordingly) and edited together with video---double system recording. I am probably only going to record 1 or 2 songs...

How reliable is this method of audio recording? I am not expecting sound quality as if it was mixed accordingly and for the most part I would be standing in the same spot.

Just trying to up the quality from smartphone footage
