LONDON'S THEATRES continue to attract Hollywood stars, the latest arrivals being Richard Dreyfuss (right) and Marsha Mason. The Prisoner of Second Avenue, written by Mason's ex-husband, Neil Simon, focuses on people failing to cope with an increasingly materialistic and financially oppressive world. Since Dreyfuss and Mason both won awards for a previous collaboration - Neil Simon's The Goodbye Girl - this has all the makings of a powerful theatrical production.
Theatre Royal Haymarket, London SW1 (0171-930 8800) to 19 Jul
THE ICELANDIC collective Gusgus dabble in music as well as art, film- making and literature. Since their UK debut a couple of years ago, they have been style magazine staples, and even reached the heights of inspiration by coining the term "ice-hop". They are not quite the successors to Bjork, but are definitely ones to watch. This one-off gig gives them a chance to showcase their third album, intriguingly titled This is Normal. With guest DJs Tim Love Lee and 16B.
