Musical band in the context of The Who

A concert, often known informally as a gig or show, is a live performance of music in front of an audience. The performance may be carried by a single musician, in which case it is sometimes called a recital, or by a musical ensemble such as an orchestra, choir, or band. Concerts are held in a wide variety of settings and sizes, spanning from venues such as private houses and small nightclubs to mid-sized concert halls and finally to large arenas and stadiums, as well as outdoor venues such as amphitheatres and parks. Indoor concerts held in the largest venues are sometimes called arena concerts or amphitheatre concerts.

Regardless of the venue, musicians usually perform on a stage (if not an actual stage, then an area of the floor designated as such). Concerts often require live event support with professional audio equipment. Before recorded music, concerts provided the main opportunity to hear musicians play. For large concerts or concert tours, the challenging logistics of arranging the musicians, venue, equipment, audience, and tickets are handled by professional tour promoters.

A bandstand (sometimes music kiosk) is a circular, semicircular or polygonal structure set in a park, garden, pier, or indoor space, designed to accommodate musical bands performing concerts. A simple construction, it both creates an ornamental focal point and also serves acoustic requirements while providing shelter for the changeable weather, if outdoors. In form bandstands resemble ornamental European garden gazebos modeled on outdoor open-sided pavilions found in Asian countries from early times.

A jug band is a band employing a jug player and a mix of conventional and homemade instruments. These homemade instruments are ordinary objects adapted to or modified for making sound, like the washtub bass, washboard, spoons, bones, stovepipe, jew's harp, and comb and tissue paper. The term 'jug band' is loosely used in referring to ensembles that also incorporate homemade instruments, but those are more accurately referred to as skiffle bands, spasm bands, or juke (or jook) bands (see juke joint) because they do not include a jug player.
