Lady Gaga's Las Vegas residency will comprise two separate shows

Lady Gaga's $100m (£77m) Las Vegas residency will consist of two distinct shows, organisers have revealed.

The main feature will be Lady Gaga Enigma, described as a "brand new odyssey of her pop hits".

She will also perform a regular Jazz and Piano show, featuring stripped-down versions of her own songs alongside classics from the American Songbook.

The star, who cancelled her recent world tour over health concerns, will make her Vegas debut on 28 December.

Tickets for the main show will start at $82 (£63), rising to $505 (£389) for premium seats, according to pre-sale information on Ticketmaster.

Announcing the two-residency last year, she promised the shows would be "unlike anything Vegas has ever seen before."

Artwork for the Enigma concerts, unveiled on Tuesday, seems to suggest a futuristic, neon-spattered setting.
