I don't know much about the French band The Sideline Haters, but I can tell you about the music
Their EP Who Shaves The Barber? offers 3 tracks, starting with The Sideline Effect. The opening passage has a doomy edge spiced up with a dash of Oriental sounds, but then they storm off into a fast death metal frenzy. Vocals in the tradition of Cannibal Corpse & co meet a more modern approach in the guitar department. Tasty Cull kicks off with a short spoken words passage which seems to come from an old movie, then head into a mid-paced death metal tune. For the title track they speed up, but add some breaks and mid-tempo parts. And later surprise the listener with more twists and turns.
The EP might contain just 3 tracks, but the quality level is quite good and even sound-wise there is nothing to complain. The French quartet started in 2014 by guitarist Allan 'M-Slay' and bassist ╔lodie 'Ch!ing'. Allan is also responsible for the recordings at his home studio, mixing and mastering of Who Shaves The Barber?.
