For their debut album, the members of The Shelters got as good a helping hand as it gets: Tom Petty gave the band the keys to his recording studio and an invitation to open up for his band Mudcrutch on tour. The Los Angeles four-piece earned every ounce of Petty's support with heavy rock 'n' roll chops that reflect its love for the pioneers of California rock, including The Byrds, The Doors and The Beach Boys.
