After a brief hiatus, Glasgow-based indie rock band The Fratellis are back with a new album. Best known for their 2006 hit “Chelsea Dagger,” the group has recently released a third record, We Need Medicine. The group gets back to the earlier forms of rock and roll, and thus their music is simple and full of energy. After a busy year of creating the record and headlining festivals in the UK, they will be at Webster Hall on Nov. 1 and World Cafe Live on Nov. 4.
