Artist Alerts and Delete SMS Messages

Does anyone know a good application that allows you to add artists to it, and then receive updates from them (IE, upcoming concerts and CD releases and the like)?


Also does anyone know an applications or widget that will allow you to delete all of your SMS messages by just pushing 1 button? I would really prefer an application that you can set it up so you just have a widget that once you push the button it deletes all SMS messages, sent, received, and drafts?

Any advice would be greatly appreciated.
