Quiz Show, Traverse Theatre Edinburgh, until 20 April In an age when millions of people spend hours every week watching television quiz shows, asking tough questions about what they do to us is one of the most significant tasks theatre can take on, and Rob Drummond, creator of thrilling "reality" stage shows like Bullet Catch and Wrestling, is the man for the job. Written to launch the Traverse's 50th anniversary season, Quiz Show is his first straight play, which he neither performs nor directs.Watch a stellar cast - incuding Jonathan Watson of Only An Excuse - bring Drummmond's vision to life, in this production by award-winning Traverse associate director Hamish Pirie. Sympathy for Mr Vengeance, Eden Court Inverness, 6 April Any new converts to South Korean director Park Chan-wook after his ravishing English language debut Stoker would do well to check out the first in his celebrated Vengeance trilogy to see where all the fuss started. First released in the UK a decade ago, this twisted revenge tale, revolving around kidnapping, corporate malfeasance and black-market organ transplants is gruesome and gorgeous in equal measure. The subtitling - unless it has been redone recently - doesn't provide nearly enough information to make complete sense of what's going on, but that just makes the end results even more enigmatic. Peter Thomson: Cobalt Wall, Compass Gallery Glasgow Peter Thomson is a painter and always an intriguing artist. Like Steven Campbell before him, he is one of the most fertile of many Scottish artists who have taken their inspiration from the dream landscapes of surrealism where strange and unexpected conjunctions can occur. Scottish Chamber Orchestra: Harold in Italy, Usher Hall Edinburgh, tonight; City Halls Glasgow, tomorrow Robin Ticciati continues his Berlioz theme with the SCO in a performance of the idiosyncratic French composer's symphonic masterpiece Harold in Italy. This is Byron's Childe Harold expressed musically through the prominent solo viola, played here by Antoine Tamestit. Webern's overture to Der Freischutz and Schumann's Spring Symphony add a German perspective to a programme soaked in heady 19th-century Romanticism. Tel: 0131 228 1155 (Edinburgh), 0141-353 8000 (Glasgow) The Bluefields, Stereo Glasgow, 7 April The Bluefields style themselves simply as "an American rock band from Nashville, Tennessee" but it's probably fair to call them a Southern country-rocking supergroup, in that their line-up comprises Georgia Satellites frontman Dan Baird, Jason & the Scorchers guitarist Warner E Hodges, Joe Blanton, the one-time singer/guitarist with heavy rockers The Royal Court of China, and drummer Brad Pemberton, also of Ryan Adams" backing buddies The Cardinals. Together, they have produced two albums of souped-up righteous rootsy rocking just begging for live performance and consumption.
