The snappy version:

Tenor saxophonist Mark Hanslip emerged as a key player on the London jazz scene in the mid-2000s, rehearsing, touring and recording with groups such as Outhouse, Nostalgia 77, Jonathan Bratoeff Quartet and TOM-MIX (featuring the late drummer Tony Marsh), working with major figures including Steve Lacy, Kenny Wheeler and Bob Brookmeyer (as a regular member of Hans Koller's large ensembles) and freelancing with pop bands.

Now based in Manchester, he currently plays with improvising group HTrio, who recently toured with US trumpeter Nate Wooley, drummer/composer Johnny Hunter's quartet, organ trio The Revival Room, and HRH with Paul Hession and Federico Reuben. He is also engaged in doctoral research into generative systems for improvised music at York University, supported by WRoCAH. 

The less snappy but more accurate, first-person version: 

I started out playing on the Birmingham jazz and improvised music scenes, working regularly in groups led by local musicians Steve Tromans and Chris Bowden, and was an early member of Hans Koller's large ensemble, appearing on 2 CDs in my early 20s (one with soprano legend Steve Lacy). After moving to London in 2002 I helped co-found the Loop Collective, and became a busy player on the jazz scene. Since the I've appeared on around 30 CDs with various groups including Nostalgia 77, Outhouse/Ruhabi, Twelves, Jonathan Bratoeff Quartet, Alcyona Mick and others. Live work included tours and many festivals in the UK, Europe and the US, radio broadcasts for the BBC and others, and residencies in The Gambia and Canada.

In 2008, after a few years of being a 'sideman' in composition-orientated groups, I felt the need to focus more on my own musical development and found myself gravitating more towards the improvised music scene. I quickly formed the trio TOM-MIX with bassist Olie Brice and late drummer Tony Marsh; we completed a Jazz Services UK tour in 2009 which also included quartet gigs with guests such as pianist Veryan Weston, flautist Neil Metcalfe and Paul Dunmall, and turned out to be more or less a second musical education!

In 2010, following many informal sessions and gigs around London, I recorded the CD 'DosadoS', a set of improvised duos with Malaga-based percussionist Javier Carmona, which was eventually released on the Babel Label this year and warmly received by the UK, European and US press, getting four stars in Downbeat Magazine among others. Through Javier I met and played several sessions with laptopist Federico Reuben, and in 2010 I also formed a trio with Birmingham-based pianist Mike Hurley and renowned drummer Mark Sanders.

These days I'm based up in Manchester and play in a mix of improvised and semi-improvised groups, the most active of which are Johnny Hunter Quartet, organ trio The Revival Room, HRH with Paul Hession and Federico Reuben, and a duo with young rising drummer Emil Karlsen. More noisily, I also play live with laptop and solo saxophone with laptop.
