Keeping Riley This septuplet group mixes many instruments to arrive at a poppy, uplifting brand of song. The lead vocals harmonize well with the up-and-down melodies of the rhythm guitar and background addition of a saxophone and an occasional flute. They are currently on tour in support of their new album released in May. With The Upside of Down, Israel Darling, Jacob's Ladder. $10-$12, Tremont Music Hall, www.tremontmusichall.com (Chris Triplett)
