If you thought Asher Roth was done you may have been a little mistaken. He’s back to actin up with Justin Bieber and Chris Brown on his new mixtape ‘The Greenhouse Effect pt 2″. If you can’t remember who Asher is you can remind yourself by listening to “I love College”. He has a moment before Bieber hit it big with Scooter Braun. I’ve had my own run in’s with Roth in the Philly area. If there is one thing I know…he’s definitely a real artist and a pretty cool guy. Take a listen to “Actin Up”. Smart marketing to have Bieber and Brown on the first track.
