uptight

adj. annoyed, pressured, tense (Informal)

Up-Tight was the breakthrough album for Stevie Wonder, released in 1966 (see 1966 in music) on Motown Records' Tamla label. The album features the U.S. Top 5 single "Uptight (Everything's Alright)", which Wonder co-wrote with Sylvia Moy and Clarence Paul, the album's producer. The tracks on Up-Tight were the beginning of Wonder's development into a mature recording artist, independent of his earlier "Little Stevie Wonder" moniker and his image as a young Ray Charles imitator.
