Journey into the night on the jazz scene anywhere and you’ll find people you’d never even imagined were there playing like their lives depended on it.

Subterranean by nature, nocturnal by instinct, they thrive on the spontaneous, and instigate creative situations that in time mutate into the music of the future. They could come from anywhere. Jamming, they play gigs starting ever later in the evening, eventually surfacing as night becomes day with a visit to a studio and an album that often or not causes a stir.

Guitarist Hannes Riepler is one such musician who, for the past two years, has been organising weekly concerts and jam sessions at Charlie Wright’s club in Hoxton, a hub for musicians on the up and up, and for visiting luminaries passing through London wishing to let off a bit of steam in John Nash’s congenial bar a short stroll from where the Bass Clef fulfilled a similar role in the 1990s.

Riepler is 33, from Austria, and is influenced by the likes of John Scofield and Kurt Rosenwinkel. His debut self-penned album The Brave just released by Huddersfield indie jazz label Jellymould matches the guitarist, whose roots are in the acoustic period of jazz from the 1950s and 60s, to a strong band. His fellow Bravehearts include Troyka’s Kit Downes; Ma’s saxophone hard hitter Tom Challenger; newcomer bassist Ryan Trebilcock; and Kairos 4tet’s drummer, Jon Scott. Recorded in the spring of 2010, Riepler arrived in London via study in Amsterdam more than half a decade ago, and honed his sound by checking out the scene all over London playing with young stars along the way including the late trumpeter Richard Turner who died in tragic circumstances last summer, and who The Brave is dedicated to along with Riepler’s dad.
