After your music has been superbly mixed it will be sent to a dedicated mastering engineer
Having another set of ears to make the final changes, with dedicated expertise, world-class mastering equipment and room acoustics always gets the best final results.  
I send my mixes to studio for the final touchs to be made, rather than mastering myself. This is included in the price.

Artist Highlights

I mixed & mastered Shristi Jade’s latest single ‘Us’ featured here.  Currently making waves in the UK R&B world her songs were played on Radio 1 during 2018!  Produced by Noza Apollo who has worked with Craig David & Lady Donli amongst others. 

I was trusted to mix Emmanuel Nwamadi’s live version of his Sade cover ‘The sweetest Taboo’. His performance of this song gained him a place in The Voice UK.  His audition received numerous accolades and reached over 2 million views on YouTube!

He continued to woo the audience and judges taking him up the final.  Check out the video his performance! 

My mix of his cover song can be heard below. 

French Soul Party is another band that I have worked with.  I recorded, mixed and mastered their single French Kissing over 2 days at Signal Chain Studios, in west Yorkshire, which was played on BBC Introducing after the band uploaded their single to the site.

It was so liked by the presenter that it was passed up to more popular stations, and eventually reached the Radio 1 playlist!
