A power trio with the guitarist on lead vocals is a popular record-company lineup, as the guitarist and singer usually are songwriters. Therefore, the label only has to present one "face" to the public. The backing band may or may not be featured in publicity. If the backup band is not marketed as an integral part of the group, then the record company has more flexibility to replace band members or use substitute musicians. This lineup often leads to songs that are fairly simple and accessible, as the frontman has to sing and play guitar at the same time.
