Good band name, good name for pubs, restaurants, boating companies, trade merchants. But tough to assess since those types are offline businesses and may not care about paying a high price for a domain. It is a surprise that there is not a business named "london wind" already. The business that buys the domain and use it as its business name will have to spend time associating the name to the business, instead of associating the business to the name.
IMO, max value in the low $xxxx
