How do I convert this active record query to a rails 3 query

The following SQL:

select * from videos v
left join artists a on a.id = v.artist_id
left join users u on u.id = a.user_id
left join genres g on g.id = u.genre_id
where g.name = 'Acoustic'

is the equivalent to (which works):

Video.find(:all, :conditions => ['genres.name = ?',
'Acoustic'], :include => {:artist => {:user => :genre}})

However, I know that the rails 3 active record query uses the .where()
clause. How can I convert the above to something like:

Video.where({:genre => 'Acoustic', :include => {:artist => {:user
=> :genre}}}) <==== Does NOT work. What am I missing?

What about:
Video.includes(:artist => {:user => :genre}).where(:genre => 'Acoustic')
?
