This appears to be a data quality issue — the string 'Not Pizza present Luke O'Brien' reads as event listing format/metadata rather than a performer name. The structure ('X present Y') is typical of promotional listings, not artist names. While 'Luke O'Brien' is a generic name that could refer to someone, and 'Not Pizza' could potentially be a band or promoter, this exact phrasing is not a verified performer identity. No information found on 'Not Pizza' as a real band or artist.
