With actor and House of Blues co-founder Aykroyd in attendance, Mohegan Sun held groundbreaking ceremonies for its new 39-story Earth Hotel Tower.
The tower, which will be the tallest in Connecticut, will include 920 rooms, including 261 with a House of Blues theme.
Set for completion in October 2010, the expansion will also feature a spa as well as a House of Blues restaurant and music venue with a capacity for 1,500 people.
