Dublin Popstar and Sweetheart. Terrible Teeth. Debut song 'Teenagers' is a rapturous fusion of the swagger of hip hop and funk and the primal angst and frustration of indie rock. 'Bad Theatre' an EP released mid May 2018, features similar mixtures, with influences drawing from as wide as Frank Ocean to The Smiths. Greg Tisdall is a 19 year old boy with a fond penchant for light pink and purple colours. For the Youth. By the Youth.
