LARRY Coryell has been described by writer Whitney Balliett as "the most innovative guitarist since Charlie Christian".

Having played with such major names as Chick Corea, John McLaughlin, Charles Mingus, Jack Bruce and Eric Clapton, Coryell's on-going project is Bombay Jazz.

Thanks to the enterprising National Centre for Early Music (NCEM), Coryell brings Bombay Jazz to York tonight. He will be joined by Ronu Majumdar (flute) and George Brooks (saxophone) to blend jazz and classical Indian music. Call the NCEM box office (01904 658338) for more details.

You can also pick up details of the NCEM November Jazz Weekend, November 23 to 25, which will feature Polar Bear, Acoustic Triangle, Liane Carroll and the University of York Jazz band.

Another hot guitarist, Gary Boyle, will be at the Black Swan, Peasholme Green, tonight (01904 679131). Ex-Leeds College of Music, Gary has worked with the Brian Auger Trinity (Wheels On Fire), Mike Westbrook and John Dankworth. His own band, Isotope, made several albums and toured internationally.

The big attraction at Wakefield Jazz tonight will be the Gilad Atzmon Quartet (01977 680542) and the band will also be at the Whitby Musicport Festival on October 20 (0845 373 2760).

Jazz In The Spa celebrates 20 years of Saturday evening jazz tomorrow night. The Savannah Jazz Band will play and the venue is the Trustees Hall, High Street, Boston Spa (01937 842544).

Bejazzled (Don Lodge and Tim New) will play for chill-out Sunday lunch, 1pm to 4pm, at the Revolution Bar, Coney Street.

Meanwhile, the Blue Flies will buzz your brain and tickle your dancing shoes at 2.30pm at the Victoria Vaults, Nunnery Lane, York (01904 654307).

On Monday, J Night Hull will present Flamenco Express at the Hull Truck Theatre at 8pm (01482 323638).

The Leeds College Of Music concert season at the Venue continues on Tuesday with the Northern Underground Orchestra, featuring Tim Garland. This explosive 13piece features top soloists Gwilym Simcock, Mike Outram and Paul Booth among others, with vocals by Hannah Jones. Details from 0113 222 3434.

On Wednesday, Scarborough Jazz (01723 379818) presents local favourite Frank Brooker on saxophone and clarinet, with Peter Elsdon (keyboards).

Raul Midon, A World Within A World (Blue Note) is a new CD by a guitarist/singer/songwriter who has been likened to Donny Hathaway and Stevie Wonder. On other self-penned songs he also sounds like Craig David (All Because Of You) and Jose Feliciano (The More I Know), hence rave press reviews.

With multi-tracking, Midon moves from Bobby McFerrin-style vocalese (Peace on Earth) and street-corner doo-wop, to the dense, close harmony acapella which would not be out of place on an album by Take Six (Ain't Happened Yet).

Although on jazz label Blue Note, Midon is jazz-lite but soulheavy, with the upbeat swagger of Brit bands Incognito and Brand New Heavies heard in the 1980s.

Raul Midon's gorgeous voice is gorgeously produced by Joe Mardin (son of Arif).

Saxophonist Dan Stern's Traces (Kvetch Records) has soul of a higher spiritual and artistic nature.

Part 1 (Traces) features hardcore jazz saxophonists David Liebman, Tim Garland (see Leeds College, above), David Binney, rhythm section and Stern over 5 tracks.

The range of reeds covers soprano, alto and tenor saxophones, plus clarinet and bass clarinet.

There is some exciting and emotional playing from all concerned, but this is jazz with the studied dischords and angular themes of some of Stern's admitted influences.

Stravinsky and Leonard Bernstein are particularly evident, elements of Bernstein's rhythmic and melodic devices from West Side Story surfacing on Super Saturate and Synthesis. The latter is also a fiercely swinging piece (think The Jet Song from WSS), while others pieces dip in and out of tempo from time to time.

Inspired drumming is by Asaf Sirkis (in Wakefield tonight with Gilad Atzmon's Quartet and with Tim Garland at Leeds College on Tuesday).

Part 2 (Mirrors), has solo Stern over-dubbed on saxophone and clarinet, the additional electronic treatment often bringing the interwoven, melodic lines close to the sound of a church organ.

The clarinet/saxophone evocation of bird-song on Around Kyrie pays homage to Stern's Messiaen studies, while other pieces have origins in Palestrina and Perotin.

If you enjoyed the liturgical sounds of Jan Garbarek/Hilliard Ensemble outings, plus postColtrane saxophone explorations, Traces is for you.
