Bassist, keyboardist, producer and songwriter with a special love for music from the 70s and 80s. Specialising in Rhodes, piano, vintage synths, 80s sounds, melodic basslines and synth bass. I’ve released and produced multiple records, performed in a Genesis tribute band and work across rock, pop, funk, alternative and progressive music.
My primary service is recording keyboard parts for your music – from piano and Rhodes to vintage synth leads, pads, organs, strings and 80s-style synth textures. I can work from a specific brief or take a more creative role, developing parts and sounds that complement your arrangement.
I also offer electric and synth bass, as well as songwriting, arranging and full production. My background as a multi-instrumentalist means I approach session work from a producer’s perspective, always thinking about what the song needs rather than simply adding another part.
I started out making progressive rock music but over the last 5 years I have covered many different genres including alt rock, synth pop, indie pop and funk.
I have a BSc in Music Composition & Technology, professional studio experience, and toured the UK as keyboardist with Genesis Visible Touch. As an independent artist, I’ve written, arranged, recorded and produced three full-length albums, working with everything from synths and drum machines to live musicians and a 12-piece string orchestra.
That experience also means I can help with the bigger picture. If you have demos, unfinished songs or an album that needs direction, I can help develop the arrangements, instrumentation and production and guide the project towards a finished record. I can also help with creating content for social media.

check_circleVerifiedReally nice job even though it was a quick demo but i can't wait to see his work on the whole thing now that I'm sold!😆 (might sound weird but I was burnt from some other producer so I was hesitant but he still was kindly willing to work with my unusual proposal!). Also answered all of my 5 billion questions :D You can trust him!👍

Worked with Bartek on a little rap project of mine. Very versatile producer, caught all my ideas on the fly even though hip-hop wasn't his go-to genre. Put my vision into life and also contibuted some fantastic input. Had fun throughout. Class act, highly recommend.

Worked with this guy on numerous occasions. He's contributed as a bassist, keyboardist, and composer. Truly a brilliant, open-minded guy with a great sense of humor, a great ear, and tons of great musical influences. He works well with 80s style pop, rock, and even prog! It's a bargain!

I hired Bartek to play bass on a couple of tracks - was truly blown away with what he came up with! Highly recommended.

I have worked on several projects with Bartek, one in particular where I hired him on keys. He is a great musician, creative and very easy to work with I'd 100% recommend him. www.russwilsonuk.com

I hired Bartek to help me out with some bass and keys. I sent him my demo track and when it came back it was like a dream come true. Now my song sounds better than expected. He threw in some inversioms and made the chords come alive. His bassline really tied the song together and he added some extra funkiness that my demo was lacking. I'm definitely going to work with him again. He can do it all!

honestly a brilliant musician to work with!
