Ultrafast science has reached the natural, attosecond, time scale of electron dynamics, with routine generation and application of attosecond pulses. High harmonic generation (HHG) in atomic gases has emerged as the primary table-top source of attosecond pulses, and has been extensively studied in the past several decades. In recent years, HHG in transparent solids has emerged as a topic of intense interest in the ultrafast community, both as a means of potentially bright and more compact XUV sources, but also for its ability to report on the driven ultrafast electron dynamics itself. In this talk I will give an overview of experimental and theoretical efforts in HHG in solids, and discuss our current understanding of the generation process in terms of a multi-step process of driven electron dynamics in k-space, on the band structure.
