"Thank you so much for bringing the magic of 440-Gypsy Jazz to our 30th Anniversary benefit on Wednesday evening. Your music creates just the right mood for people to feel celebratory! One of our guests--an older gentleman at that--started to dance to the music, which is a testament to the power of your tunes."

440 - Gypsy Jazz

Here is what people say about the CD...

The blend you achieve with the clarinet is extraordinary. Your CD is very musical and very precise. Intonation is flawless. You must be very proud of your music.   — Christopher Baird

I listened to your CD on the way home. I love it!  It cheers me up.   — Kathy Larsen

Reminds me of music from Woody Allen’s film. This is the music I like and you guys executed very well. I want two more as presents for my friends!   — John Kloubcher

I just wanted to compliment you on your beautiful CD. I love all the music, but the pieces that you wrote yourself -- "Why Why" and "Reflections" -- are extraordinary! The passion and musicianship of your pieces remind me of the great Cuban music in Calle 54. It's a real treat this time of year with the chill in the air outside to have something warm and beautiful to listen to inside! Many thanks,   — Mary Beth Hagen

I listened to the CD yesterday, and I found it very enjoyable. I didn't grow up with 'gypsy jazz,' and in fact have scarcely been exposed to the idiom. I do remember a Stephane Grappelli duet with Paul Simon (called "Hobo's Blues," if memory serves) on an early Simon & Garfunkel album. I've always loved that tune -- the joy of the playing is so palpable. The same is true of your album, where all the tunes are played with great joy and brio. I know that your covers are 'standards' of the genre, but I was rather more excited to hear the original compositions. After all, the jazz classics are already out in the world, but this will be the first time people will get to hear your music.   — Bruce Sesnovich

As a Grappelli/Reinhardt fan, I can vouch for/heartily recommend this CD. Excellent music and I believe Tomoko's playing compares very favorably with Stephane's. The original compositions are especially nice.   — Dino LaChiusa

440 expands the gypsy jazz tradition of Django Reinhardt and Stephane  Grappelli with danceable swing standards from the era of Cole Porter,  George Gershwin & Benny Goodman as well as originals by the band.   Their toe-tapping, snappy, hot jazz, swinging style is a delight to experience. 

Toe-tapping Snappy Hot Jazz

Jack Soref, graduate of Berklee College of Music,  became captivated by the music of Django Reinhardt after attending the International Django Reinhardt festival in Samois-sur-Seine France in 2002. Jack spent half a year living in Paris France in 2011, where he jammed with the legendary guitarist Boulou Ferré and violinist Florin Niculescu. Jack can be seen regularly in the greater Boston area playing Django's music, with a myriad of local musicians. Out in the wider world, he has performed as an accompanist for Jazz Manouche luminaries like Joscho Stephan, Tim Kliphius, Gonzalo Bergara, Jason Anick, Olli Soikkeli, Adrien Moignard, Ben Powell, Aurélien Bouly, and Titi Bamberger.
