This co-operation led to Thomas joining Blaze during his composition and production process for the 2012 album The King of Metal, and its subsequent tour.

The King of Metal tour with Blaze Bayley took him across Europe and further cemented an ongoing musical relationship with the singer.

[12] In early 2014, Zwijsen released Nylonized, a 12 track album featuring an eclectic mix of song arrangements (ranging from The Who to Adele), original compositions and guest artists.

3 original compositions are featured on the album, co-written with drummer Nathanael Taekema, including a nine-minute flamenco-metal opera called "Perfect Storm".

[15] Divide & Unite contains 11 original compositions in a flamenco fusion style, supported on Drums and co-composed by Nathanael Taekema for six of the tracks.

An Extended Production by the name of "Treasure Island" was released simultaneously containing four tracks plus hidden bonus of various rock arrangements for classical guitar and trio.
