Who Else! is the seventh studio album by guitarist Jeff Beck, released on 16 March 1999 through Epic Records. The album reached No. 99 on the Billboard 200 chart and marks the end of a decade-long absence of original material from Beck since the release of Jeff Beck's Guitar Shop in 1989. Stylistically it showcases the first of his many forays into electronic and techno music, deviating notably from the straightforward instrumental rock and jazz fusion of previous albums. Fellow guitarist Jennifer Batten, having cited Beck's influence on her playing on a number of occasions, is featured as a collaborator and subsequently joined him on tour for three years.
