Hi Sohan, You would be the best person to answer your question of how to proceed :-). >From your original query term "musical events in New York" rewriting to "musical nights at ABC place" OR "concerts events" OR "classical music event" you would have to build into your knowledge base that "ABC place" is a synonym for "New York", and that "musical event at New York" is a synonym for "concerts events" and "classical music event". You can do this using approach #1 (from the Berryman blog post) and the approach #2 (my first suggestion) but these results are not guaranteed - because your corpus may not contain this relationship. Approach #3 (my second suggestion) involves lots of work and possibly domain knowledge but much cleaner relationships. OTOH, you could get away for this one query by adding the three queries into your synonyms.txt and enabling synonym support in Solr.
