Classical music meets physical comedy and a drama in a pie shop - it can only be the Festival Fringe.

Here's five highlights happening this week:

London Philharmonic Orchestra Chamber Group, St Michael's All Angels Church, Victoria Road, tomorrow
Made up of musicians from the London Philharmonic Orchestra, this chamber group performs together all over the South-East when their schedule permits. With a programme to include Mozart, Sphor and the Schubert Two-Cello Quintet, they will be joined by local pianist and rising star Warren Mailley-Smith. Warren has given recitals at the Wigmore Hall, the South Bank Centre and performed for the Royal Family. The chamber group is under the direction of one of the LPO's most senior members, Santiago Carvalho. Starts 7.30pm, £10/£8, 01273 709709.

The Specialists, Gardner Arts Centre, University of Sussex Campus, Falmer, tomorrow and Sunday
A brand spanking new show from the Edinburgh Fringe award-winners Pluck - "the world's most musically challenged string trio". Theirs is a world where popular classical music collides with supersilly physical comedy and remarkable talent meets demented humour. Pluck was formed in 2002, when violinist Adrian Garratt got together with violist Jon Regan and cellist Sian Kadifachi. All three performers are trained classical musicians who share a desire to do more than play the instruments. They've since taken their show all over the world, winning more awards than you can shake a stick at. Starts 4pm, £9/£7, 01273 709709.

From Within, Friends Meeting House, Ship Street, Brighton, tomorrow to Monday
A moving play exploring one woman's journey coming to terms with her son's autism and one boy's journey of coming to terms with his world. It stars local actress and playwright Sinead Gillespie, who was inspired to write the play through her own experiences as a mother whose son has Asperger's Syndrome, a form of autism. Sinead aims to "de-mystify some of the preconceptions of autism" in a piece which is accessible to all. The piece, by Sigma Productions, began touring last year to sell-out audiences. Starts 7.30pm, tickets £7.50/£6, 01273 709709.

Present, Marlborough Theatre, Princes Street, Brighton, Monday-Sat, May 20
A one-act black comedy about "living for the now". During the christening of his godson, a man comes face to face with his every regret. Thirty years on, the godson is confronted with a few home truths of his own. Dark, stark and wholly inappropriate, this production contains material that relates to life and death. If you are adversely affected by these issues, Continuum theatre company recommends you attend. Starts 8pm, £8/£6, 01273 709709.

Enemies Reunited, Pokeno Pies, Gardner Street, Brighton, Thursday
This is comedy writer Kerrie Fuller's first play, which looks at what happens when life doesn't go to plan. Jules is a single girl who works as a temp in the city. Life seems to be going along pretty smoothly until she gets an invite to her school's ten-year reunion. Suddenly her life doesn't seem up to scratch. Should she find out what happened to her old crush? Or should she stay at home? And yes, you've read correctly, this play will be performed in a pie shop. Starts 7pm, £6/£5, 01273 709709.
