Yo-Ki Swing is a joyful collection of mostly original swing tunes by Tomoko Iwamoto. Tomoko and her 440 band members unroll a sweet swing soundscape with beautiful musical colors; it is simultaneously exciting and relaxing to hear. Highly recommended CD! -- Dave Reiner, Director and Founder of Fiddle Hell Massachusetts

1st CD "Why Why"

Label: CdBaby.

Label: CdBaby.

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. 

Tomoko Iwamoto, a leader of 440, has been in Boston jazz scene for more than 30 years. Being a "jazzy" violinist with a strong classical background, she expanded her repertoire in jazz, rock, pop to world music, toured with Hypnotic Clambake, while studying Jazz Composition and Arranging at Berklee College of Music. During her recent trip to Europe, she jammed with world renown gypsy jazz musicians; Tcha Limberger & the members of Les Violins de Bruxelles, and Chris & Julian Brunard. She appeared as a guest soloist with Mood Swings Orchestra and Women In World Jazz, and collaborated with modern jazz guitarist, Chris Mcdermott.

Tomoko has her own melodic vocabulary that she has created within the gypsy jazz context. Not an easy thing to do. It reflects the strength and bravery of her character. It shows she has lived some life and her stories are subtly silhouetted through her music. Such a pleasure!  -- Chris McDermott, guitarist, singer, songwriter, and producer (www.chrismcdermott.com)

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.

We saw 440 at the Homegrown Coffeehouse and were blown away. I grew up in a Dixieland Jazz household and had never heard of Gypsy Jazz. I loved how beautifully the violin and clarinet blended together and I also loved the endings of their songs...and how they were so precise and tight. Tomoko's compositions were beautiful.

Here is what people say about the CDs...

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
