Formerly known as Tendertraps, Scars On 45 is an indie/acoustic band consisting of members Danny (vocals/guitar), Aimee (vocals), Nova (piano), Stu (bass), Matt (guitar), and Chris (drums). The band originates from Leeds/Bradford in the UK. The Heart On Fire Songfacts states that after being ignored by the British music industry for a number of years, the band secured a deal with the US with Chop Shop Records, a division of Atlantic Records. The label is owned by Alexandra Patsavas, who is the music co-ordinator for Grey's Anatomy and she chose "Heart On Fire" to promote the 2011-12 season of the ABC medical drama series.
