Researching possible songs

My first task of researching for my music video is choosing a suitable song. I found this very difficult because it needs to fit a certain criteria to be acceptable for its use. The band or artist needs to be British and unsigned. The song needs to have clear structure/sections, lyrics, and a change in mood/feel. Lastly, it needs to be a good quality sound recording. As a result, it took me a long time to find a suitable song, especially due to the common occurrence of finding many unsigned British bands with good songs- but are let down by having bad quality sound recordings. My task was to therefore find these small exceptions of those who have good songs and quality recordings.
I will be working on this music video project with Hammad, and these are the songs we found.

Song 1: B l a c k B i r d - f e v e r

Black Bird is a solo artist and producer from Manchester and is unsigned. His song 'f e v e r' is an Alternative R&B track that fuses elements of pop, soul and electronic music. There are clear sections of a verse and chorus with changes of intensity- e.g. from how the drums fall out and come back near the end section. The song has lyrics which I believe can be visualised into a music video.

Song 2: tbyalx - Pressure U

Pressure U is a Downtempo/Chillwave song made by a British duo called 'tbyalx'. There is not much information about them so I assume they are unsigned. The song is well very produced and sounds industry standard to me. The song has clear sections and changes in mood and energy such as the slow ambient verse which turns into a bass heavy hook with a fast paced drum beat. The lyrics- which are sung by a female vocalist giving it a less agressive/more chilled out feel, I think are about a relationship. This gives us a starting concept idea.

As of this present moment we cannot decide between these two songs, and will give it some more thought and research into any other possible songs.
