Preheat oven to 425°. Season lamb with salt and pepper. Mix together olive oil, mustard, chopped rosemary, thyme, parsley and garlic. Spread evenly over the meaty part of the racks of lamb.
Place in a roasting pan, fat side up and roast for about 20 minutes for medium-rare (about 125°-130° internal temperature). Allow to rest for 10 minutes before carving.
While lamb is resting, prepare the sauce by combining the red wine with the balsamic vinegar and sprig of rosemary. Bring to a boil, then reduce to a simmer until sauce is reduced by half. Swirl in butter. Adjust seasoning by adding salt and pepper, if necessary.
Cut each rack into 4 double lamb chops. Place on a platter, or place two double chops per person on individual plates, with a drizzle of red wine sauce and a sprig of fresh rosemary.
