Khalil is comfortable mixing and mastering in the analog and/or digital world, depending on project needs.
He has worked in Lebanon and Germany with local and international artists including but not limited to: Rita Redshoes (Portugal), Max Herre (Germany), The Trouble Notes (USA), Ray Garvey (Ireland), Ziad Rahbani (Lebanon), Fairouz (Lebanon), AURORA (Norway) and Kabat (Czechoslovakia).
Using audio science as a tool to enhance artists' musical ideas makes him a favorite with artists, who trust his taste and understanding of their musical direction to deliver nuanced work.
He helped designing and implementing audio technical structure for studio spaces where he creates his best conditions for capturing and mixing music and has partnered on these kinds of rooms with TrueBusyness and Riverside Studios. At these and others, like Jazzanova Recording Studio, he also records, mixes and masters albums in Berlin. He maintains his connection with the Middle Eastern production domain by working remotely on projects with Notta Studio and Audio Addicts, where he has recorded and mixed many artists in Beirut.
Khalil listens to music as an engineer, but also as an artist, composer, arranger, studio musician and regular listener. Driven to improve the quality of results for all kinds of listeners using audio science and musical understanding, he has gradually been pushed from the engineering seat to the role of producer. In Cologne he produced the latest album of 5vor12, a rock band whose members were thrilled with his ability to understand, record and strengthen their group sound.
