'Liar' starts with a prominent electric guitar and then the volume lowers ready for Arrow's vocals to shine. The lyrics throughout are well written and I am really impressed. The pop-punk feel really adds to the song and you can hear the emotion of frustration and anger pour out.
I don't usually like comparing artists or saying one artist reminds me of another as each artist has their own sound, style and artistry. However, I do get Paramore vibes from Arrow. I hear a slight familiarity.
Compared to Arrow's debut single 'Cult', 'Liar' seems to be very different musically which I like to see. Arrow is still at the beginning of her musical journey and at this stage, finding your sound is important. I like to see artists experiment and make every song different. It makes me more excited for future releases and this is exactly how I feel about Arrow.
