He was joined by David Harding and Martin Lueck, with whom he spun out to launch AHL, one of the most successful systematic trading firms ever.

Marlin recruited a band in 2010 ("The Whethermen") and played a series of gigs in small venues throughout the UK.

Marlin's first single was a cover of the Bee Gees disco hit "Stayin' Alive" from the 1977 film Saturday Night Fever.

In January 2011, he was chosen for HMV's Next Big Thing and as part of this event played at the Jazz Cafe in London on 9 February 2011.

In February 2012, he released his second album, Man on The Ground, and went on to support The Stranglers around the UK and Europe on their Spring tour.

The release was accompanied by a limited edition box set containing book of artwork by Colin Brown, the Scottish Collage artist and double LP.

The latest incarnation of his band is a trio, The Melomaniacs, consisting of Marlin, Paul Silver on keys and Kim Murray on guitar.
