Record Time is a charming and knowledgeable US music magazine that is slightly unclassifiable too, if you really have to pin it down. In any case, if you buy old records, buy this.
Record Time is broadly focused on discovering neglected, forgotten, obscure and unusual records from all genres and providing a bit of detective work to share stories about them and the people who made them, for as long as its publisher (blogger and musician Scott Soriano) says, 'the records are still affordable in used record stores.'
