Dear Gary,

Regarding your recap earlier this month of the biggest musical acts from each U.S. state:

We may not have representation in Congress, despite paying taxes into the national treasury, but there are 600,000 American residents in the District of Columbia and a rich history of contributions to American music from here.

No mention of D.C.'s top artist? :)

Hi Ray,

Good idea! Let's follow-up on our "Born in the U.S.A.: 50 Stars from 50 States" feature posted over the July 4 holiday.

Pop fans might not fully realize his contributions to American music, but the late Duke Ellington may be D.C.'s finest musical export. He passed away in 1974 after leading his band for 51 years. The jazz great won 12 Grammy Awards from 1959 to 2000 and has had nine recordings inducted into the Grammy Hall of Fame. Also: a Pulitzer Prize (1999), the Grammys' Lifetime Achievement Award (1966) and appearances on a (22-cent!) U.S. stamp (1986) and a commemorative U.S. quarter (2009).

Another D.C. artist that became an icon? Late R&B legend Marvin Gaye.

For younger generations,
