American music mogul Dr Dre looks back in good health as he returns to the music studio, just a day after leaving the hospital following a brain aneurysm.

The 55-year-old music producer and rapper can be seen looking healthy and confident in a photo taken by his colleague, music producer Focus which he shared on his Instagram page on Saturday, dailymail.com reports.

Dre kept his look casual as he returned to making music with a simple black hoodie and matching black jeans.

The Chronic hitmaker, who normally sports a clean-cut look, showed off a close-cropped salt-and-pepper beard as he sat at the mixing console.

He was surrounded by producers and rappers celebrating his return to good health.

‘My Big Bro is Super Good!!!’ Focus gushed in his caption. ‘We Working’ he added, before clarifying that he took the photo and was in the studio with Dre and the others. He included the hashtag ‘#AFTERMATH.’
