Addison Groove Project returns to New York City for two gigs at the Lion’s Den, tonight and tomorrow. These shows will open a string of dates that will lead into a west coast tour in April. Meanwhile, one of the group’s compositions will appear next Tuesday on ‘The Shield,’ which airs on the FX Network (tune in to discover which it will be). Beyond that, AGP will route back to the northeast in May with a date at Mexicali Blues on May 7 in which Melvin Sparks will appear with the band before a tour-ending show at Boston’s Paradise the next evening.
