I can contribute to your talent and make your song stand out!!
Singer-Songwriter, Session Singer, Session Guitarist, Lyricist
You have a song that needs vocals? Don't look any further, I'm here to get the job done. My goal is to bring your project to the next level! Emotional and versatile, strong and powerful voice, I will adapt my expression to your song, its lyrics and dynamics.
Strong Catchy Attention Grabbing Hooks. I write what you want stuck in your head. Whether you’re chasing a hit or telling your truth, I’ll help you say it in a way that hums in the back of your mind all day. I also do sound design frequency tuning, give me your desired song and I can tune in it to make it alive.
30 years making artists sound great. Professional trained and worked with producers such as Peter De Havilland (Oasis) and indie labels such as Flat Records in the UK. Predominantly work with up and coming artists, who want a professional, radio (streaming) friendly sound, that will make their art pop.
I believe great mastering starts with listening, not just to frequencies, but to you. My priority? Protect your art’s essence while elevating it to its fullest potential. No shortcuts, no presets: just obsessive attention to detail. I ask questions, not assumptions. Your vision guides every tweak. Mastering as it should be: unhurried and soulful
I’m a mixing and mastering engineer with a First Class degree in Music Production and Sound Engineering from Middlesex University, and I’ve refined my approach through the mentorship of Steven Jones (Bleed From Within). Whether you’re working on metalcore, deathcore, or heavy rock, I’ll make sure your music sounds competitive and hits as hard
