There are multiple artists using the name Delivery.

1. Delivery was a British blues/progressive rock musical group, formed in the late 1960s. The band was one of the wellsprings of the progressive rock Canterbury scene.

Founded in 1966 as Bruno's Blues Band by guitarist Phil Miller, his elder brother, pianist Steve Miller, drummer Pip Pyle and bassist Jack Monck, the band gigged around London for a few years. In 1968, saxophonist Lol Coxhill joined them, and the band's name was changed to Steve Miller's Delivery. In 1969, the band teamed up with blues singer Carol Grimes and bassist Roy Babbington replaced Monck. The resulting line-up recorded and released one album: Fools Meeting. Although Grimes wanted to appear as a band member, the record company released the album under "Carol Grimes and Delivery". In 1971, Pyle left the band to join Gong and was replaced by Laurie Allan (who also later joined Gong). Soon after that, the band broke up.
Phil Miller went on to found Matching Mole with Robert Wyatt and Dave Sinclair, but a new Delivery line-up was assembled in the spring of 1972 consisting of the Miller brothers, Pyle and Richard Sinclair (bass and vocals), then Steve Miller's bandmate in Caravan. The band played a few live shows in August/September that year, but with Steve Miller being replaced by Dave Sinclair (from Matching Mole and Caravan), the band changed its name to Hatfield and the North. A final Delivery performance took place in November 1972 for the BBC's Radio One In Concert series, with an unusual line-up bringing together the Miller brothers, Pyle, Babbington, Coxhill and Sinclair, the latter on vocals only.
Steve Miller went on to release two shared (rather than "duo") albums with Coxhill for Virgin's Caroline budget label in 1973/74.
Roy Babbington, who had played with the Keith Tippett Group and Nucleus in 1971-73, went on to join Soft Machine from 1973-76. Laurie Allan rejoined Gong a couple of times, most notably appearing on 1973's Flying Teapot, and later Barbara Thompson's Paraphernalia.

2. Delivery is a techno producer from the US. In June 2014, he released the 12" Drama.

3, Post-punk band from Melbourne, Australia. Formed in lockdown by Rebecca Allan (Gutter Girls, Blonde Revolver) and James Lynch (The Vacant Smiles, Kosmetika), and now rounded out by Lisa Rashleigh (Soursob), Daniel Devlin (Heir Traffic, House Deposit) and Seamus Whelan (The Vacant Smiles). On their debut EP "Yes We Do", Delivery unveil a restless and neurotic blitz over four tracks that fuses urgent garage-rock together with nervy post-punk and weirdo new-wave smarts. ‘Yes We Do’ leans into off-kilter home production quirks as opposed to the group’s fully realised live sound, each track powered by a propulsive combo of robotic programmed beats mashed with live drums against a stack of sniping tunnel-vision guitars and buzzing synthesisers
