Classical music lovers around the world will be able to sit in a "virtual" hall to listen to an online performance by a leading orchestra.
The orchestra will perform to a worldwide audience
The Royal Liverpool Philharmonic will perform what is billed as the first professional music concert in a "virtual online world".
An orchestra spokesman said it was important to explore and embrace new technologies and audiences.
The cyber event will be seen by visitors to Second Life website.
Liverpool Philharmonic chief executive Michael Elliott said: "Orchestras today are committed to reaching out to make their music more accessible to encourage new audiences.
"That means exploring and embracing the opportunities presented by new technology. For us Second Life allows us to tap into a potential global audience.
"It's also a lot of fun and it certainly adds a different dimension to the more traditional visit to a concert hall."
The event is planned for 14 September.
