The guitarist explained that today's music scene needs an artist like the 21 songstress to set an example to young and emerging acts.
"She's great. She's a shot in the arm for this industry," Slash told The Independent.
"She writes her own music that's not at all contrived. And she's managed to sell loads of records which makes her a great example to the younger artists.
"Like Amy Winehouse, she's organic and real. It's great to have that happen at this moment when everybody else is so synthetic."
Adele recently confirmed that she has recorded the official James Bond theme for Skyfall. The track will debut in full on October 5.
